Thanks, but not sure it's super useful for a patch in the middle. It
just adds a dependency, and I'd need to rebase. Providing an ack
or reviewed by would probably be more useful.
But given how slow the mm side is going, honestly not sure what the
target or plan is for inclusion at this point in time.
