Just FYI, there is an alternative effort to propose a JSONPath
standardization based on a consensus of JSONPath implementations, see
https://cburgmer.github.io/json-path-comparison/ for the comparisons.
They're currently putting together a Proposal A,
https://github.com/cburgmer/json-path-comparison/tree/master/proposals/Proposal_A,
including an ABNF grammar and test suite, and have invited comments.

Best regards,
Daniel
