Is this not already the case for all tightly coupled code? This RFC
proposes to make the least-coupled code in PHP more coupled, so soon,
you'll be able to say the same for interfaces (if this passes).

I don't understand this RFC. Symfony is a mess in that a class
requires an interface, even if there is only one implementation. PHP
shouldn't fix that, Symfony should rethink how they're doing
inheritance.

Abstract classes solve this problem perfectly. It's part of the type
system, it's type-hintable, it's mockable, and it's pretty easy to see
what inherits it as people who inherit it already know what the base
behavior was when they wrote the code.
