My concern with something described as a "smart, time window schedule" is
that it does not sound to me like a schedule that developers can rely on.
Being trigger-based is nice in theory, but if we routinely wind up
struggling for 3-4 hours to land particular components, and as a result miss
the window for the build and wind up running up against build+1, then such a
"smart" trigger isn't actually helping us, as compared to having a regular
build every 8 hours of whatever's most current in the archive.

Even if we have reason to believe a particular image won't be promotable,
having these images regularly produced - and at greater frequency - is still
useful for tracking down regressions.

Maybe these issues are already taken into account and will be part of the
announcement on Monday?
