This is probably not hugely important in the context of WM as a writing tool, but I personally use monospaced fonts for all writing, regardless of whether it's technical / programming / other, and a lot of the fancier mono fonts offer ligatures. I think they really help with clarity and show intent behind symbol combinations, especially in technical writing. It also doesn't affect source input or output so it's safe in that regard.

Example being Fira Code: https://github.com/tonsky/FiraCode
I'd love to see support for this, but I'm not certain how hard it is to implement.
