Reminds me of the first four Beatles UK LPs being releases on mono CD as they were recorded and initially releases in stereo but were meant to be heard in a mono mix down from two & four track masters. Initially Rush had a problem with their songs in surround but changed their minds later on. I'm hoping Supertramp's members have a similar change of heart. Otherwise do as they did for Pet Sounds & Odessa and have it available in stereo & surround.
I doubt Supertramp know much, if anything, about their music being available on the new HFPA BD-A, let alone the whole surround thing!
