Why are you ignoring restrictedTraverse? That's exactly what the Traversable
interface (of which it is a part) was built for...

It is.

aq_parent is very much an implementation detail, whereas restrictedTraverse is
an interface who's implementation may or may not need aq_parent to work.
Squishdot and its postings implement the Traversable interface but do their
aquisition wrapping differently...

That, I suspect, is purely by chance. I see now reason why getPhysicalRoot isn't
protected identically to restrictedTraverse('/').
