Comment (by Simon Charette):
Carlton, I agree that it's its own issue and that it's highly related to
#18305.
I'd say the fact that `save(force_insert=True)` doesn't work **is** a
duplicate of #18305 and the fact `save()` doesn't result in the same
optimization as #29260 when a primary key default is defined in MTI is an
omission of #29260.
