As with your previous RFC, I approve of this in principle, but am
frustrated how little time has been spent considering the edge cases, such
as the ones I mentioned here: https://externals.io/message/117487#117487

It seems to me that we've got an increasingly complicated set of states a
property can be in, depending on whether it's been declared with a type,
without one, or not at all; whether it's had a value assigned to it;
whether it's been unset; etc. If I am struggling to follow the distinctions
between "declared", "defined", "initialised", "dynamic", "nullable" etc,
how will users who start with PHP 9.0 understand why some situations
produce errors and others do not?
