See my other post, it is ok that it hasn't been adopted because it is
obsolete. We do have a seamlessly integrated lossless mode since v8.

What you call "professional area" here is a speculative domain,
so that fits perfectly. They use unreal technologies, because they
themselves are unreal. You are healed by nature, or by consciousness,
while the medical market is just a fake for clueless people, so again,
this fits perfectly.

Speculative domain, unreal, nice fit.

You have not understood.
With "existing JPEG images" it means files created with prior JPEG
versions in real use. Again: Your standard papers are not the reality.
The lossless branch is obsolete, as mentioned, and "JPEG-LS", for
that matter, is also obsolete.
