Not answering Mike directly here, but the thread in general...
IMHO, it's too early to have this discussion.
Alpha has not even been released...
Instead, before:
2010-09-14 Beta Change Deadline
Features 100% Complete
We should look at the state of things and decide if we should revert
(just like any other feature thats not ready).
So, please everyone test and file bugs and note your cases where things
don't work and we can evaluate before the Beta Change deadline.
