that is also problematic.
by harcking around it it gives the ironic command a different behavior to the rest of osc.
osc does support microverions it just does not support automatic versin negociation which is
what you are hacking in.

i do agree that it would be nice to have support for version negociation where by you could do somehting like
--os-compute-api-version=auto to opt in to it but automatic microverions detetion does make it harder to do help
text generation unless you make "openstack --cloud=my-cloud --os-compute-api-version=auto help server create" call out
to keystone get the nova endpoint and then lookup its max microversion when you render the help text.

with that said if adding --os-image-api-version=auto was enough to get the glance team to fully adopt osc
then i think that would be better then partioning the community between osc and legacy client.
osc should behave consistently for all projects however so adding negocaiton for ironic and not for other services
is not a good thing imo but i guess you were able to do that as ironic is integrated as a plugin correct?
