This means wiping out history again; in TopGit, you would ideally
checkpoint all the branches within the patchset, then just tg update
your branches. It's another matter that the former is now difficult to
do easily.

Hmm, to a degree I misunderstood your idea. You would still need quirky
commands to update the references when you make a new commit, to go to a
certain patch (at which point git will start acting a bit annoyed since
it's not on a branch), etc. Other than that, I can offer only my gut
feeling.  ;-)

There are already some patches in the wild to make gitweb topgit-aware;
I don't see why is the latter a problem.

Yes, I finally understood what do you mean, sorry for being a bit dense.
