Totally agree (on all points). I've done all the genuine 2-ch DVDA into a DVDA 2ch folder.
I'm now going to go back and get all the 5.1 and also create some 2-ch versions of those that didn't have one.
That way I have it 'all ways' in due course.
As I'm currently 3.0 in the system, I have not great push to get the 5.1 playing (have to replace the missing rears for that....maybe some on wall DSP's

) but the Dune would get me apodizing via the HD621.
However, I would expect M to release the G68 firmware that Bob said would be coming just the week after I buy a HD621 to achieve the same.
Quite honestly, I'd just like to get trifield working properly for now(HQ that was a subtle hint !!!!)
cheers
