Stall is still a thing, but less effective I think. Stall teams can run Pursuit, Shed Shell and untrappable mons to mostly limit Goth from doing too much for free- but doing so will likely leave the team weak to some other wallbreaking threat, like Mixed Primal Kyogre. It's not really Goth by itself, but rather Goth in addition to all the other big threats to stall imo, as its impossible to cover all of them and means that the wrong matchup can easily screw you over.
Other common Pokemon on stall include Ferrothorn, Toxapex, Tyranitar, Giratina-A, and Yveltal as well as the rarer Mega Slowbro, Alolan Muk, and Ditto. Defensive Primal Kyogre is more of a balance mon than a stall one.
