Only if we want to use framesync. If we don't care about synchronizing
the streams, then we could drop FS and just use a custom activate
function which forwards output status only to the *corresponding* input.

Maybe also with printing a warning if the refstream parameters do happen
to change, since at that point we know it wouldn't be in sync.
