you can't get anything done if nobody wants to do the work
I remember a guy who wanted to make company documentation in LaTeX. Well yes it is great tool and we could put it in a git repo and render nice documents for the customers easily. Downside was 15-20 sales people who were not thrilled to use it and spend time learning how to use it.
I'm not sure though why sales people would need to edit it.
My discontent with LaTeX for documentation is that searching it sucks. I mean, you do get literal search for words, but if you want something smarter... PDFs don't interact well with searching tools we have.
Another problem: interactive scroll. In HTML documents you can scroll sections of documents independently of each other (if you need to), so you can create ad hoc views of your documentation that could be more useful to you (eg. collapse a bunch of tables or code listings just to see the text in between).
On the other hand, if you want to print it, oh man... it's going to look so much better! :)
"Why sales people would need to edit it?"
Because there were no dedicated people writing documentation, there were developers and sales people - that was it. Non technical documentation so "how to use the system" was going to be written by sales people.
Lots of times in a company you work with what you have and finding and hiring "technical writer who has experience or wants to work with LaTeX" I would count as hard task.
I mean, I have a feeling that if a company asked a technical writer to learn LaTeX, they would probably do it, even on their own time. It's a tough market, and learning LaTeX enough to produce something isn't a huge effort (also, there are a bunch of tools that prepare the boilerplate code for documents). But I can see how sales people might not have been impressed by such prospects.
(To be fair I am mostly depending on an incremental build and I'd say Java turns around in 2s, Javascript in about 20s. One of those breaks my chain of thought, the other doesn't.)
PS: Luckily, I'm not a frontend dev :)
