As a bot dev, I occasionally run into issues where rooms get confused because their features no longer work, only to later find out that the issue was that they changed the permission for a command or permission to %, accidentally excluding bots from them. It'd be nice if command error messages for such commands had a distinction between
access denied and access denied because this room has custom permissions. That way I can catch that message, have the bot autoreply to it, and I don't have to debug it every time it happens
