BTW I believe frames should not go out at hw rate value 0, I did some
test a while back on this rate and its not exactly reliable, you will
get very funky behavior on it. Are you seeing that rate being used on
legacy-hal? Last I asked about it too its not something people know
about as being desired effect. I could be wrong but it'd be
interesting to see where this is used correctly.

So its slow because using rate 0 takes a while? If indeed you don't
see a valid use for this rate I'd say to completely disallow it and
use BUG_ON() on it.
