+1
It seems there is a fair amount of favor for adding the new names.
There is some resistance to removing the old ones.  I would be happy
to deprecate the old ones, but leave them in until we release a new
major release (i.e., NumPy 2.0.0).  We could start creating a list of
API/ABI clean-ups for whenever we find a compelling reason to release
a new major version.  In the meantime, we can leave the old names in
and just add a deprecation note to the docs.  Once we are ready to
release 2.0, we can release a 1.x with deprecation warnings.
