I am not 100% sure, however, 4:2:2@hl is not an option in several encoders I use, so I assumed that it should not be used, I maybe wrong
I just got a "white paper" from Sonic Scenarist and it states:
The 8-bit 4:2:0 Barrier
The HD DVD and Blu-ray Disc specifications list a large number of constraints upon the video codecs that they employ.
Amongst that list one fundamental item (the profile adopted) has a massive impact on the overall quality that’s attainable
by inferring (amongst other things) that the bit depth and sampling format is 8-bit 4:2:0.
According to current technology I won't be able to use my 4:2:2 colorspace files directly in blu-ray delivery format - will have to wait for the next generation of discs because blu-ray specs are final.
