Dang! Polyphonic modulation?? This CLAP thing looks very good. For anyone wondering, here is an official overview video. Very impressive. Being an open standard, it has a chance of taking off, as long as enough DAW and plugin developers decide to support it. Obviously Steinberg and Apple, respectively, will not cooperate, at least not initially. Pro Tools? Dunno. I see no point in all these standards that fulfill the same task to varying degrees. Would be better to have one to rule them all.
I'm guessing supporting some of these features will require effort on both sides, the DAW and the plugin developers. Maybe Steinberg and Apple will updated their respective VST and AU standards to copy some of the features of CLAP. Either way, a bit of competitive innovation always means the users win.
