Another thing is about existing flavors configured for these

and if any of these are found, we report a warning meaning those
flavors
need to be updated to use traits rather than capabilities. Would
that be
reasonable?
I like the idea of a warning, but there are features that have not yet
moved to traits:
https://specs.openstack.org/openstack/ironic-specs/specs/juno-implemented/uefi-boot-for-ironic.html
There is a more general plan that will help, but its not quite ready yet:

As such, I think we can't get pull the plug on flavors including
capabilities and passing them to Ironic, but (after a cycle of
deprecation) I think we can now stop pushing capabilities from Ironic
into Nova and using them for placement.
Forgive my ignorance, but if traits are not on par with capabilities,
why are we deprecating the capabilities filter?
I would like to know the answer to this as well.
