I have copy-edited the description. There are still some details that we could sort out. Please check.
The use cases are not explicit in the description right now, and perhaps it would be useful to mention the main ones. Some VSTs are instruments, and this feature would bring the sounds of these instruments to The Grid, right? Other VSTs provide audio effects or MIDI data, and I guess people interested in this feature also would like to to use those? What is your main motivation here, the instruments or the effects?
I guess it would be useful to link to Note Out module for The Grid, and perhaps even Containers within the Grid ? I may be completely wrong, but maybe the development of container modules for The Grid would help solving some challenges brought as well by the development of a module to “contain” a VST plugin.
I don’t understand what this means. 
About “potentially bitwig devices too”, this is out of scope for this request. And I don’t see why this feature would make patches visually more readable.
