Deprecating sure.  Actually dropping is not so easy I think.  The switch
is not transparent to the guest, which implies live migration
compatibility isssues.

So the only thing we can do is blocking it for new machine types (3.1+).
Then, in a bunch of years when we deprecate 3.1 & older machine types,
we can actually remove it.

I remember we even discussed that a while back ...
Oh yes:

Somehow never ended up being merged.
