Ah, that. Already fixed, I believe.

I don't expect XP to go away any time soon. But do I think that the
number of fresh XP installs in combination with Linux will be fairly
limited. And general lack of hardware enablement will eventually kill
off XP on raw metal.

I think it's ok that we have stop-gap solutions in place for
interoperability. But I wouldn't want to waste all our resources on
designing for the past. I'm much more interested in making sure that
single-boot Linux is doing the right thing.

I agree that this is a don't-be-broken option and I would prefer it the
other way around (I know that's the plan for the next release. I just
hope the distributions get things right).
