one thought: if we first encounter <Self as Trait>::Gat<u32> which normalizes to <u32 as Trait>::Atpit and then later encounter <Self as Trait>::Gat<Self>, which normalizes to <Self as Trait>::Atpit, this change causes us to not define Atpit anymore, does it?
While it seems fine to not support that for now, I would like to have an open issue/test for that

oof right, we had this issue with structs before -.- I knew why I didn't want this check. Maybe I should move the recursion check even later
