I am all for removing getters.
The question is when to do that so not to have a BC break mid-version. And
if we keep the getters for PSR-0 for now, then whether it would be weird to
not provide them for PSR-4.

In Krautoload I always had the philosophy that getters are a wrong idea,
because having them introduces assumptions on implementation details, that
we rather want to avoid.

On the other hand, removing stuff that was temporarily added, or reverting
to a previous state of the class loader, seem legitimate things to do.. or
not?
