So I'm picking up this thread again to explain my objections further now
that it's not vacation.
The issue is making it easier for reviewers to care only about a subset
of of the tree. Which I see as being useful. The problem is, how do you
Git commit message is something we live with forever, and is something
that requires code originators to get tagging right. We can't even get
people consistently tagging email threads, so doing this with commit
messages doesn't seem to be a winning battle. And doing it with an ever
evolving list of tags means it ends up just becoming line noise in our
So lets go after the real problem, selecting subsets of reviews, which
is really a gerrit problem (made worse because we are on an ancient
gerrit. 2.4 is really no longer suitable).
Gerrit has the ability to put watches on file regex for watched projects
(though only for email, because it's an expensive query).
Gerrit 2.5 implemented the ability to put UnifiedDiffs in the emails,
which if we did on New Change emails would let you build client side
filtering to flag for directories or files that you have.
Gerrit 2.8 implemented *secondary indexes* which means the file regex
can be made available via the web UI.
So the real solution is gerrit upgrade, which is currently held up on
the WIP patch. But I think we're getting to the point where we need to
decide if that one feature is worth holding up all the rest of the
features that we are missing that would help with our review overload
