Elixir has had dialyzer + type hints for years

The point in my career at which I used jq the most was when I was doing a lot of work with Elasticsearch doing exploratory work on indexed data and search results. Doing things such as trying to figure out what sort of values `key` might have, grabbing ids returned, etc.

Second to this, I've mostly used jq to look at OpenAPI/swagger files, again just doing one-off tasks, such as listing all api routes, listing similarly named schemas, etc.

From what I've seen in the companies I've worked for, this is fairly consistent, but naturally I can't speak for everyone's use-cases. At the end of the day, I don't think most people use jq in places where readable or maintainable would be most appropriate.

I installed spacemacs 5ish years ago and have added maybe 20 lines to my configuration since then. None in the past 4 years. It's really overstated the amount of maintenance that Emacs requires.
