Perhaps I missed where this changed, but my recollection is that we also
back-patch bug-fixes, and I don't think we should change that.

If the perception issue is that customers aren't comfortable with
changes being made in the main repo which are due to adding testing then
we should consider having an independent test repo which is also able to
be run through the buildfarm.  Perhaps we would be able to consider
having a more relaxed policy around that repository also, along with a
way to distinguish failures on the main repo vs. failures from this
other repo (where the issue might be the test itself rather than an
issue in the code, or it might be an issue in the code that the test
exposed but isn't yet fixed, but allows people to see that their
independent changes on the main repo aren't what caused the buildfarm to
turn red).

Thanks!
