I'd suggest moving this patch to the end of the series. If someone is
bisecting an issue and they land somewhere in the middle of this
patchset, you'll be advertising properties to userspace that aren't
fully functional which may cause unexpected test failures (and make
bisect decisions harder).
Generally we like to "flip the switch" to make new functionality visible
only at the very end when all the internal plumbing is complete.
