Both approaches have their ups and downs, but both slow down
development:
* Asking rel-eng for overwrites takes time.
* Asking rel-eng for a tag takes some time too. And I'm afraid
that with an inflationary number of tags things get unclear for
other maintainers. They don't know what to build their packages
against or when to use which tag. It requires a lot of
coordination between the different parties.

The major advantage of a custom tag for me is that we have a consistency
plan. If something goes wrong, we can just throw away all these builds
and turn back to a previous state without downgrading packages and
introducing epochs.
So we both agree about the advantages of custom tags, but we are talking
about the development versions here and not about stable releases. In
the branches that are under development we would not do a bugfix against
the "stable" tag. Instead, all updates are supposed to target
development. If we really needed a bugfix in a development branch, this
could easily be done with early branching.

Again, we are not talking about stable releases. But if someone does
large updates in the stable releases, I agree they should use a custom
tag.
