The problem with developing for anything Apple-related is that they keep changing requirements for developers. Getting the plugins to work in Logic was a lot of pain and honestly, I’d much rather make music or record some new samples than troubleshoot yet another system. But I’m not saying no, it’s just that I need to get over my hate for the process first 
Regarding AAX - it’s up to Avid at this point. It’s been about six months since I started trying to get in touch with them but I’m not loosing my hope.
