This feature is awesome.
However I noticed that it works without using the feature gate at all.
I create a minimal repo to reproduce:

These feature gates do not actually matter, as they will be insta-stable after const_trait_impl gets stable. As long as you are not able to use this without having const_trait_impl enabled, it is fine.
