I would be interested to hear if this is a workflow that suits people that write mathematics papers or other complicated TeX documents. My TeX code is very macro heavy (I know some mathematicians who define almost everything through macros so that they can rewrite the paper quickly) and, as a result, I've never really seen the benefit of unicode mathematics.

To go one step further: I think writing Greek letters (or, for that matter, any Latin letter that does not have a standard mathematical meaning) is an anti-pattern in mathematical prose: I think it is much, much better to write \coercivenessSymbol than \gamma or the unicode variant for the same reasons I would not name a floating point number gamma.

Looks like it already have been implemented: https://tex.stackexchange.com/a/28033/133525

I mean having any macros name you want, even Unicode.

So you can even have \γ macros. But if you want to write \coercivenessSymbol (even on the blackboard) we cannot stop you - after all it gives you pleasure.

My conclusion about this feature: https://github.com/kiwi0fruit/sugartex/issues/1

SugarTeX is tweakable. You can write your own Panflute Pandoc filter that additionally defines new non-standard replacements alike yet defined in SugarTeX. But I dont know if you need it: LaTeX macroses are valid SugarTeX too after all and they are quite powerfull.
