Who says we need to implement it as g++ does? DMD could implement it

The derived class controls everything. You cannot take control away from
the derived class, it just can't be done:
class A
{
private void cantCallMe();
}
class B : A
{
override private void cantCallMe() { butICanCallYou(); }
private void butICanCallYou() { /* do impl */ }
}
so far, private virtual functions == annoyance. I haven't seen anything
to prove otherwise yet.

Private overridable functions come with a guarantee that hooks can never
be called from an unknown/uncontrolled context.
