Which suggests you don't understand MQA...
Its just a new way to compress high-samplerate PCM, its not going to "improve" the quality of the audio compared to high quality lossless encodes that we have today.
The only chance it potentially has is if it can compress to smaller sizes and deliver better quality as other compressions, but thats all.
Note that the company uses the term "MQA" for a variety of technologies, including their audio mastering tools, which they tout as improving quality.
But the MQA audio format itself is no magic. Its just a way to encode extra frequency information ontop of a 48kHz encode - which is no better than just encoding a FLAC at 192kHz to start with from a quality side.
Sounds somewhat like AAC's Spectral Band Replication (SBR), or DTS X96, which are encoding tools to "boost" the sample rate without encoding their data completely (which would take much more bitrate).
In any case, to the original topic - due to licensing requirements, it seems unlikely that it would be supported anytime soon.
