Note that in August of this year it will become obsolete. In august
we'll be dropping support for debian-10 old qemu and thus bumping the
minimum supported qemu to at least qemu-4.2.

Additionally we have a whole separate machinery for probing the
migration capabilities via the migration parameters, so you can
theoreticaly replace it by that code, especially since you'll need to
set the multifd capability when attempting the migration anyways.
