Ok, if Python is acceptable, I'll use its stdlib to do "fancy" things.
Part of this is because I want to assert that unnecessary fields don't
exist and that sounds…unlikely to be possible in any maintainable way
(assuming it is possible) with regexen. `jq` could help immensely, but
that is probably a bridge too far :) .
