Deprecate private variables and methods?
Fragment of a discussion from Manual talk:Coding conventions
We're actually trying to use them in new code because they help in separating abstractions and give us better better control over proper interfaces to access data. You can't force people to uses accessor methods if they still can access class variables directly. Unfortunately, due to PHP's low entry requirements, many PHP programmers know nothing about proper OOP/OOD and produce such opuses instead.
