But under the proposal we do not have to test entire branches. Instead
of testing all rows for all columns, we only test a usually small number
of rows against some of the columns. Together with a reduction in the
number of machines running release branch tests (as others have also
suggested), the net effect may well be a drop in the total testing load.

Stable doesn't mean perfect. It only means no worse than on the last
release. And in practice each release will be better, so the bar for
stability keeps getting higher. Eventually, all of the issues you
mention will be dealt with, but releases should not be held waiting for
that state of perfection.

The Boosters as a whole should only be concerned with testing for full
releases. If particular projects want to do library specific releases,
it is their responsibility to do the testing of those releases.
