I can't see a reason to put checks at runtime to prevent people from using
They are documented as private. That means the slot is not meant to be used
outside its circle of friends (outside the library or module).
If one wanted to be nasty, he could write a macro to change the name of the
private slot at every minor release...
But that would gain nothing, really.
The point of guaranteeng API and ABI compatibility is to make programming
easier. So, ensuring people shoots themselve in the foot when they pull the
trigger is not the library developer buisness.
