Indeed, and MQA has nothing whatsoever to do with the encoding elegance of MP3 and AAC... Heck, since the uptake of FLAC has been so slow I would say MQA is the obvious technology - for the next century!
Incidentally, the LAME open-source MP3 project changed developers in about 2006, and the old 3.97 version has an ABR encoding quality IMO much better sounding than what is obtained from today's versions. Fraunhofer also got the 'magic' correct with their early (pirated) encoder - which sounded excellent (for the bitrate).
