Perhaps, but SpaceX's history to date hasn't suggested they want to
have two versions of the Falcon 9 going at the same time. In fact,
their payload user's guide touts how the Falcon 9 is going to be even
safer for customer payloads because it has been built around the idea
of man-rating the launcher.

As for the mention of schedule importance in another thread, the way
the launch manifest (when it was still published with such
information) kept showing the launch dates of various customers
slipping, and the way things continue to seem to slip (even prior to
this recent anomaly) suggests that anyone currently a SpaceX customer
isn't worrying much about schedules. Yet anyway.
