WordPress MU needs something similar. 'mu-plugins' never get their
activation/deactivation hooks called, because there is no concept of
activating or deactivating mu-plugins (you just add/delete the .php
files from the mu-plugins directory). All it does is run include() on
wp-content/mu-plugins/*.php.

Some plugins (particularly those that add DB tables) break with the lack
of these hooks, and I would like to see WordPress MU work differently in
that area.
