Hi,

There was one drawback, it was worse for one-frame hickups:
http://lists.freedesktop.org/archives/mesa-dev/2014-February/053888.html

That alone wouldn't prevent using it IMHO, as the
heavier-scenes-that-last-for-minutes is a valid use case. I just got
tired of trying to push it, when it took nearly three months to get a
review.

Nowadays I prefer to contribute to projects where patches don't go
unnoticed for months at a time.
