But if the job of validation is down to the UI, the
engine can be more
efficient.
The current LV2 spec says that the plugin's "engine" should validate
its inputs anyway... IIRC, there is a draft/experimental extension
that allows the host to specify that it will take care of that, but I
haven't seen it used yet (and probably it should be that way until it
gets "serious enough").
However, I have no idea whether how much performance gain you would
obtain from that and/or if it allows to do stuff that you can't do
now.
In my (admittedly limited) experience in developing LV2 plugins, it
shouldn't be much of a problem.
