[LV2] should plugins somehow indicate whether they support MPE?

Hi,

could this be a good candidate for such an extension?
I designed it in 2015 but never got around to publishing it.
Reading this thread I realized it might be a good idea to do it now.
Please let me know what you think! :3

It is backwards-compatible with MIDI, by using the combination
of channel and note number as the identifier for a note, allowing
for 2048-part polyphony. This extension defines a way to send
additional parameters for those notes using atom objects.
