I think actual stenography, like court transcribers use, wouldn't be a great fit for programming, because it is designed specifically around the use case of spoken English (or whatever), and relies on shorthand for phonemes to achieve speedups. It doesn't really have allowances for punctuation and other things that are specific to programming syntax. But there's been a steady increase in the popularity of chorded keyboards with a small number of keys, which is kind of like stenography but probably more suitable to writing code. I don't really like them myself (I prefer a 60% keyboard with macros and layer modifiers over memorizing a bunch of chords), but some people swear by them. I assume there are projects to do it in software as well if you don't want a fancy new keyboard. I'd look in that direction if you want to check this out.
