I also dislike probed_raw, for the same reasons.
Raw can't be probed safely, by its very nature. For historical reasons,
we try anyway. I think we should stop doing that, even though that
breaks existing use relying on the misfeature. Announce it now, spit
out scary warnings, kill it for good 1-2 releases later.
If we're unwilling to do that, then I'd *strongly* prefer doing nothing
over silently messing with the raw writes to sector 0 (so does
Christoph, and he explained why). But since it's already committed, I
figure it's here to stay.
