It's not widely supported because it's not technically 'out' yet!
This has been gobbled up by the developers just as 802.11n was in the early days of 'Draft N'. So everyone's using it to some degree prior to any 'official' standardisation having been ratified. I only mention it now in the hope that the Devs. seek to tinker, if they haven't already.
[HLIGHT]'Partial support' in this sense is indicative of the
partial standards that exist so far Colin! So your MS analogy of a 'finished product gone awry' is a little premature![/HLIGHT]
