shouldn't that be use 'in Groups.Commutative', @fchapoton?

I just checked, yes, that's the pattern. For example:

deprecation(35999, "the function is_CommutativeAlgebra is deprecated; use '... in Algebras(base_ring).Commutative()' instead")

or

deprecation(35253, "the function is_Algebra is deprecated; use '... in Algebras(base_ring)' instead")

I did use this pattern in these other deprecation messages when there was at least some indication that these is_... functions were used with this meaning.
But is_AbelianGroup has never been used with a meaning other than this specific isinstance test.
