You hit the nail on the head; this conflict arose because we did not
have a version policy in place earlier.  An expectation was generated
that NumPy 2.0 would co-incide with a thorough review of the API (an
exercise I hope we complete in the next year or two).

We have a simple decision to make: do we renege on the promise of an
API review for 2.0, or do we neglect the new versioning system?

Since the new versioning system has not been in use all that long (the
reason for this minor upset), we don't stand much to lose by naming
this next ABI-breaking release 1.5.
