One other thought: having a PendingDeprecationWarning is somewhat innocuous. By default, those warnings are filtered out (set to Ignore).
You have to ask to see them. It would be much different for a DeprecationWarning.

It is pretty conservative to issue a pending warning now, a deprecation warning in 2.4, and remove the duplicate method in 2.5. This is doubly true for a brand new module that has only a minimal existing code base. Not bringing it up for 12 to18 months is, IMHO, much more impactful.
