Probably not, but yes, I do want to reduce the commit load. I also
think that we essentially have a contract with our users to limit what
we back-patch to critical bug fixes and security fixes.  When we don't
do that, people start asking to have individual fixes cherry-picked
instead of just upgrading, and that's not good.  We may know that such
changes are low-risk, but that doesn't mean everyone else does.
