well if people take your instruments they can also take the necessary libs... its not that they have to get them at some unknown place in the internet.
but it would make your work easier... time you could spent on better things
looks like the next version will be even greater but don't rush it
seems like a great bunch of work
but couldn't you have found another solution for the vanilla compatibility?
something like mark those abstractions or put them in a sub-folder "non vanilla" or something?
but don't forget its your library so only your opinion matters
