I'm sorry, but this isn't something we want to support at this point.

@filipesilva, Any ETA for Addons & Library Developer mode as mentioned in Angular Connect video(https://youtu.be/uBRK6cTr4Vk?t=12m37s)?

I ended up having another CLI wrapping the @angular/cli just to have my own commands and blueprint, and I had to maintain it all the time, especially after removing Ember blueprints I had to create separate commands half using blueprints others are using schematics :/
looking forward to having this supported at some point.
