It does seem like the most reasonable thing to do.

I don't know what the wording should be changed to, then. Perhaps all
that is reset between deactivate() and activate() is everything that is
time dependent?

Note that doing this means there is no way for the host to reset a
plugin instance to a known state other than completely reinstantiating
it. I don't know if this is a bad thing (since that's the only way you
can really be sure anyway)
