The whole point of Beman's proposal is against this last statement. The
point is that each library developer should be responsible for getting
their library into the stable branch and maintaining that stability at
all times. If a library is put into the stable branch with some change
which breaks another library, it needs to be backed out until the
appropriate libraries are coordinated to work together at the stable
branch level.

The release manager is then freed to set the appropriate dates and get
out the release.
