What if you realize after x.y.z has been tagged, built and uploaded that
it has a security hole as it happend with fpc?

Subversion has a native lock command ;) One can override it, but this is
behaving really bad and I don't expect anybody to do so.

So the release manager needs to run his own git repository instead of
having the release tag in the central, fast and reliable repository? The
sad thing about this workflow is anyways, that no release manager can
test all patches because he lacks the appropriate machines so he needs
to merge patches blindly.

This is fine, but sometimes moving a tag is needed. Period.
