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.
