The only case when behavior is change is described at computeNonTrivialTypeArgumentForScopeSubstitutor The idea is to avoid depending on the presence of @UnsafeVariance and instead approximate captured types in covariant argument positions before building substitution scopes It's correct because for Captured(*) <: Supertype, Out<Captured(*)> <: Out<Supertype> and when we've got @UnsafeVariance value parameters at Out, it's ok to allow passing Supertype there. ^KT-57602 Fixed ^KT-54894 Fixed
