All the styles I've been able to find are geared towards technical writers creating software documentation. Is there a particular academic style guide you have in mind, perhaps it would be possible to create a vale style for it.
Yea that is true, I use a customized version of the write-good and Microsoft styles, but for math formulas and such something like latex is better IMO ( though possible to recreate with vale too probably)
There are quite a few academics using a markdown->latex pipeline, with pandoc or similar tools. But it doesn't seem like the vale linter is the right tool when it comes to formulae.
