It won't be useful if the standard interface is, basically, Twisted.
Stack-based solutions like gevent, eventlet get screwed over by this.

No, they don't. Gevent and eventlet can simply use this instead of their own event loops. In addition, they could install their own event loops.
Tulip separates API from event loop mechanism.
All the above frameworks will be ported to this and become interoperable - in a similar way to how wsgi works for the web.
