The concern is a combination of:

1) getting noisy emails (as Renato has mentioned - this could be fixed by
an improvement to buildbot (or our config - we're not sure where the issue
lies/can be addressed) to not email on red->purple->red). This is my
proximal concern, since that's the way most of us interact with the
buildbots - IRC and emails.

2) A lesser concern, is the ability to look at the buildbot dashboard
(grid/waterfall views) and have a sense of the state of open issues/points
of concern. With bots consistently red for long durations the dashboards
seem hard to use - it looks like everything's broken all the time & it's
not clear what are known issues with ownership and what are new/untriaged
issues that need immediate attention.
