I hope you don't take my comment as too much of an insult to your work. I consider the hallmarks of the current generation of frameworks to be component composition, framework based change synchronization (KVO, diffing, dirty checking), and the avoidance of DOM interaction (jsx, templates). Not being on the newest trend doesn't automatically make something bad and it's clear that you and your team put significant effort into your framework so I'll have to do a much more thorough investigation before I have a real opinion on it.
