Why does it matter? "Tainted by AI" seems like a cool proxy measure for something that is already measured by some existing measures.

I'm guessing the point of this is more Butlerian Jihad than identifying slop in particular? Using an AI review bot gets you on this list. Presumably, even if the fixes are artisanally designed and implemented, that is enough to "taint" the project. Personally I find that a bit juvenile, but I guess we all have different priorities.

I think overall it's probably net positive for the ecosystem to have a place where only hand crafted code is welcome, so I guess I support this existing.
