Mail is for spam-delivery, an ancient tool from a distant past ;-)

No, seriously - we have 100+ unhandled patches on patchwork, many of
them iterations on a single topic that must be cleaned up manually
(because the scripts can't).

If patches bitrot in gerrit, at least they're already build tested, and
iterations are grouped together automatically.
Which means less work for the poor soul trying to clean up.

rebase, modifications, ... essentially, it's possible to track a single
issue and its patches at a single location.

It's a special workflow, but for git there doesn't seem to be a default
workflow anyway. Specifically, there's no way to push to master
directly. Instead:
- commits are pushed to gerrit (by normal "git push" and a
commit-message hook that adds a Change-Id entry)
- commits are build tested by jenkins automatically, which registers its
vote with gerrit
- commits are reviewed by other developers
- sufficient positive review count -> commits are pushed to mainline by

We'd need bidirectional bridging that doesn't always break...

... so I'd prefer that.

People generally had a problem with accessing svn:// URLs already, so we
provided a http[s] read-only copy of the repo.
I guess we can do similar with a read-only git repo.
