permanently leaving this behind (to become more and more obsolete, and
potentially be read by users looking for the current documentation) the

Personally, I would be tempted to add the cleanup code, then remove
it again in a couple of months. That should clean up the majority of
systems, while not leaving aggressive cleanup code in a stable
release.<br>
