While this might be a reasonable default policy given the alternatives
[or more precisely, the lack of ability for hyper-user to configure such],
it still sounds a bit crude - a user would have an available MAC only if
other users were kind enough not to consume all of them?

Have you thought of adding some configurable method through which
this could be controlled?
