:-( Good to know, though.
But if you know up-front which things to make optional... you can adjust
your implementation.
So that I can write a synth plugin and be reasonably assured it will work
with "everyone's" LV2 synth host. So that I can write an LV2 host and be

Nothing more powerful than MIDI even exists for this yet. Nothing to do
with synths. + Freely
use extensions A, B, and C. If you use any extra
LV2 extensions, try to make them optional. Otherwise,
please simply call yourself an "LV2 Plugin," because you
won't work with every LV2 Synth Host.
Extensions that are not necessary to function at all should be optional
anyway, in all cases. Would somthing
like this be *so* bad?
What benefit does it have? What problem does it solve? How is it even any different from what might be the equivalent for an
"effect" plugin?
Because Synths are usually more complicated than an effect, and less
well-defined conceptually. There's presets, samples, MIDI
implementations, sound libraries, routings, effects in the sampler,
variable number of ports, various ways to pass data, etc.
If you want to start such a thing, it's a wiki for
a reason ;) It's
much easier to revise there than on the list.
...but much harder to *discuss*. ;)
