Any reason why you would use jq over Python? Certainly this can be attributed to my lack of knowledge in jq, but anything beyond a simple query is going to be done with Python for me. Beyond not having to look up query syntax, doing it in Python (or any script) is easier to read (both during and after writing it) due to auto formatting in an editor.
To give an example from another context: This is a bit like asking "why would you use document.querySelector() instead of just looping over childNodes directly?"
