And I'm not. If it's technically possible (and I'm sure it is), it
should be done. The rule is simple: don't like it - don't use it, but
don't limit the way others use Bazaar.

I think that the problem is different. In your scenario there are
problems with propagation of commit messages changes made to old
revisions, but there aren't any problems with propagation of bug
fixes. And, IMO, the real problem is that both commit messages bugs
and source code bugs are *bugs*, but they are treated differently.
