The only use case I can think of is to enforce access restriction (an alternative to
'friend' classes), faster than using debug_backtrace(). But I would prefer really
implementing friend classes/namespaces.

@S.A.N: you can already determine the caller using debug_backtrace(). Slow and inconvenient, but it
works.
