I consider that to just be a bug. Unsetting a 'local' variable should be identical to unsetting a global, as that is what actually happens (should happen). That there is a saved copy that will be restored later is irrelevant.
Same question:
Do you mean that unset can mark local variables at the same scope as unset,
that unset can remove local variables at a previous scope, or that unset in
a shell function can unset global variables?
