You missed

(4) The new interface is so awesome it is accepted immediately and
replaces the other interface.

or

(5) the new and old interfaces are combined into awesomeness.

I see (4) as unlikely, and agree that (1) is more likely.  (5) would
mean more churn, and running out of time.

So the decision to weigh is whether the new interface is likely to
result in awesomeness, and is it worth the risk.
