I'm not sure I fully understand what you're saying but, the Poke Bank server is entirely independent and not at all tied to gen 6's, all it truly needs is the game. That means even if gen6 (or the 3ds as a whole) does lose its support, so long as the next console has backwards compatibility with 3ds/ds games ( which is likely ) and a new Poke Bank app is made for it, it should be entirely possible to transfer over all data that has been stored in the old system to the new one with an update before shutting everything off. That's the beauty of a cloud storage system; as long as the Poke Bank itself doesn't lose support everything else should be able to interact with it so I wouldn't be concerned about that honestly.
But that's the thing, how long will GF support compatibility with Gen VI? Of course right now they're keeping it because people would want to transfer their Pokemon from Gen VI to Sun & Moon, but what about when Gen VIII comes out? Then Gen VI would be two generations old and not likely anyone playing it or at least playing online and breeding Pokemon in it (course some people may replay it for fun and catch a Pokemon they may want to transfer up, like a Shiny). Either they decide to save server space but stopping Gen VI support or leave that functionality alone but if it breaks they won't bother fixing it as they would have moved on by then. Or they could release a newer and better version of the Pokemon Bank, we'll call it Pokemon Cloud, where the Gen VI compatibility won't even be an option since it would be two or more generations old. OR, if in the future GF decides that Pokemon Bank isn't worth keeping up so they decide to close it down.
From Gen III to Gen V the transferring of Pokemon was within the games themselves, as long as you had the devices you needed you could transfer without needing a middle function. But since transferring to Gen VI and beyond is now solely dependent on Pokemon Bank the ability to transfer up is out of your hands and into the hands of the people running the servers who have to think of the business side of things. Oh, and also since its connected to Pokemon Bank it's no longer a free thing, you'd have to pay the Pokemon Bank yearly subscription even if you don't plan on using it. Yeah, 5 bucks isn't a lot but it's 5 bucks I could have spent somewhere else but am now paying for something which in previous generations was free. Oh, and that's not even going into people who may not have that great of an internet access, admittedly a small crowd but does that mean they deserve to be ignored? And you know what, they could easily fix this by having Poke Transporter be able to store some Pokemon in it, which I guess could be their backup plan.
I would add the Venusaur family, Blastoise family, Pidgeot family, Beedrill family as well. Having Mega Evolution shouldnt disqualified them.
Here's the problem with Pokemon with Mega Evolutions if they get an Alolan Form: Either they'd have to not change the Alolan Pokemon by a lot so it makes sense for them to Mega Evolve into their Mega Form or they'd have to create another Mega Form. It's a hassle eitherway, though admittedly Alolan Mega Evolution does sound cool and I kind of hope is a thing (which if revealed to be then, yes, you can add back in the Pokemon who was disqualified since they had Mega Evolutions).
However also Mega Evolutions is a Gen VI thing and GF right now is pandering HARD to Gen I because 20th Anniversary seems to only apply to Gen I in their eyes (or they're trying to draw back the people who left Pokemon after Gen I but got back into it because of Pokemon GO).
You guys are overfitting the data with very specific rules for Alolan forms. Not to mention that it is possible for non-Alolan and Alolan forms to coexist if they are geographically distinct. Maybe I'm just biased because I'm dying for a Dragon/Water Dragonite that keeps Multiscale. Also, I wouldn't expect Alola to be entirely free of pollution. Wherever humans go, pollution will follow. Yes, most of the islands seem pristine, but I bet there are some Grimer, Koffing, etc. in the dirty underbelly.
With regards to who's getting an Alola form, has anyone checked whether or not the Pokemon who do have an Alola form had their normal forms shown in a trailer or something prior to revealing the Alola form? Because if so, the whole discussion is kind of pointless.
While you have a point, it does defeat the purpose of having an Alolan Form. Alolan Pokemon are Pokemon who adapted to Alola's environment, there really shouldn't be a normal variation of that Pokemon unless it was brought over (like with your family's normal Meowth).
You know, I'm beginning to wonder if it was even worth trying to list which Pokemon would get Alolan Forms considering all the arguments that broke out of who qualifies and doesn't qualify.
