Well, as some other replies have indicated, it *is* a little more
complicated than it seems like it should be at first blush.  However,
I haven't (yet) had this problem with monotone, it's more of an svn
gripe that I see as a monotone possibility if tags disappear.

Precisely.

Sure, but checking out a release version to do some regression
testing, finding a bug, and accidentally committing it to the "tag"
branch seems pretty likely to me -- in fact, even *more* likely than
it would be with svn, due to the usefulness of DaggyFixes.

At any rate, I think we're all on the same page.
