To be honest, you're opening a can of worms.
We tried to discuss about it a couple of times, the last ones I remember
were during the Ussuri PTG in Shanghai where we tried to find alternatives
for not changing the os-flavors API.
See
http://lists.openstack.org/pipermail/openstack-discuss/2019-November/010643.html
for the context which was leading to https://review.opendev.org/#/c/663563
eventually ending to be abandoned as the consensus wasn't reached.
