As far as I can tell, this together with

    [PATCH 0/2] migration: Drop deprecated QMP stuff
    Message-ID: <20260108125512.2234147-1-armbru@redhat.com>
    https://lore.kernel.org/qemu-devel/20260108125512.2234147-1-armbru@redhat.com/

buries all the deprecated migration interfaces.

Opportunity to deprecate some more ;)

Yes.  This series was definitely inspired by that one, thanks for doing it
(and the fast reviews)!

Let's see if we can remove COLO first. I would treat COLO as five features
in a wholesale package.. :)
