Something not having alternatives doesn't make it necessarily nice. It's okay to wish for better even if you have something that works.
Of course not, but compared to every alternative today, jq is eons better than everything else. It's conciseness, ease of use, ease of learning all make it awesome. So as of right now, it is the nicest thing to use by far.
Personally though, I don't think I do wish for better. Jq is missing nothing that I want.
Putting that frustration on jq seems like a case of transference.
