That's one possibility, but would show the warning until the zoned
patches get merged. I'd rather have a clean build once the W=1 build is
on.

I can insert a patch removing the variable, the zoned patches get still
rebased so that's fixable. Let me know if you want to send the patch as
it's from your series, or I can do that too.

This should have been mentioned in the v2+ cover letter as well, along
with the version-to-version changelog.
