None of the existing code in Classpath that uses VMStackWalker calls
it through private or protected methods, so I'm not sure why you're
saying that having private and protected methods is a "common case".

Anyway, the reason it's done with the current "simple" semantics is to make
these calls as efficient as possible. Although your semantics would make
things more robust in the future, you have to balance that against
a (probably small) loss of efficiency.
