I made that commit after having a look at
<http://tug.ctan.org/info/symbols/comprehensive/symbols-a4.pdf> and only seeing
`\minus' from `MnSymbol' and `fdsymbol', leading me to conclude that `\minus' 
was
erroneous. Your point about text mode symbols is a good one, and now leads me to
think that switching to text mode and using `\textminus' would be the most
appropriate value (which I can confirm is both provided by `textcomp' and now
works OOTB with TeXLive 2022).

How does that sound?

All the best,
Timothy
