Hi internals,

I've sent a mail about this before, but as this turned into a bit of a
larger change (also allowing "abstract private" methods in traits) and
there's some backwards compatibility impact, I've created a proper RFC for
this:

https://wiki.php.net/rfc/abstract_trait_method_validation

Regards,
