2022-11-19 Update: It appears this won't cause a real problem.
It has already been more than 2 years since No Food for Thought rejoiced about the arrival of JPEG XL. Needless to say, the last 2 years were quite disappointing.
And unfortunately, it turns out our legal systems may keep photographic standards from catching up with this "new" century for even more years. Now, if only I could patent "software patent deliverance", perhaps we would manage to bring patent grants close enough to a halt for software to evolve!
