Because it does not actually prevent private methods in
subclasses from overriding ones in their superclasses, moves
error detection to compile time, adds overhead to every call,
and saddles you with yet another dependency.

Attribute::Protected turns subtle bugs into crashes, which is
a start when you have nothing better. But you do have something
better: using lexicals to store private methods *eliminates* the
problem entirely.

That’s what BEGIN blocks are for. (And they’re always implicitly
there when loading a module.)
