Such an outcome might be "acceptable", but could hardly be called
"desirable."

I'll note that a *big* pile of potentially useful ZODB features were
pretty much inaccessible to the Zope2 community from the date of the
first 3.3a1 release, nearly two years ago[1], until the release of Zope
2.8 last month.  This timespan, eerily enough, coincides almost exactly
with the  life of the Zope 2.7 release cycle[2].

I know how and why the loss happened (I helped *make* it happen, I'm
afraid), but I don't want it to happen again.  Moving to time-based
releases should help with the problem, but we aren't there yet, and
won't be for a year (a successful delivery in December could be a fluke).
