(such improvements are unnecessary for monolithic applications such as actually, no. Ardour has only recently started "duplicating" any of this functionality internally, and even then, its for very limited purposes. it uses JACK for more or less everything, and does not duplicate much of JACK's functionality at all. Ardour2 continues to use JACK for all audio routing, for example. that doesn't seem to have held back a bazillion other APIs, including at least 2 other "notable" (non-free) audio plugin APIs. neither VST nor CoreAudio are extensible, but this does not appear to have held back hundreds of plugin developers from creating plugins for those APIs. if we're looking for reasons why plugin developers do not develop (as a rule) for Linux, i think that the extensibility or non-extensibility of an API is probably not the place we'll find the answer(s).
