Opinion. Likely controversial. The fact that we need jq highlights that we are missing this functionality in shells. I argue that these days (nested) structured data is as basic requirement as having scalars, arrays and associative arrays (which bash has). It hurts my eyes seeing five line of assignment to variables where each one runs jq to extract that particular field from a data structure.
