Comment 8 for bug 309682

What's the value in copying (tagged) revisions into a branch if they aren't reachable from the head? Wouldn't it be equally sensible to drop the tag from the branch when cloning it (and ignore it when displaying it)?

I guess there's a performance cost to pay when checking the integrity of the tag data. In that case, maybe that validation could be done by check (and fixed by reconcile)?
