Yes, of course this depends on the host. But presumably an LV2 host
would then also deactivate the plugin and later reactivate it to reset
it to a sane state? At least that's what I thought these callbacks were
for. IIRC that's how it works in Qtractor (Rui, please correct me if I'm
wrong), and that certainly makes sense to me. I didn't test this with
Ardour, though.

Otherwise, how is an LV2 plugin supposed to know that it has been
suspended and should prepare its internal state to be switched back on
again? All the host knows about the plugin are its ports, so it's
limited in what it can do. Only the plugin itself knows about the extra
cleanup it might want to do when being switched off and then back on
again, no?
