I tried out #unicode-math in #LaTeX for a week and after excitement of having vastly improved readability source code I feel so frustrated about having to configure many detail and still not getting optimal experience typing formula.
And I found this:
UTN #28: Nearly Plain-Text Encoding of Mathematics
https://www.unicode.org/notes/tn28/tn28-6.html
So, many #UnicodeMath would be just yet another things, although promising, that I would not adpot in real life.
