Yes, but if that's a major concern, just tell the host not to do
silence at all. (Config option for any serious RT host.) The host
hardwires all SILENT controls (or whatever we use) to "not silent",
and all plugins will run full on all the time. No optimisations and
no surprises.

Yes, it should definitely be optional, and I like the "there's always
a buffer" approach in this case too. If you don't care, you *really*
don't have to care at all; just process your audio.
