The numbers was what I was mainly thinking of, so thanks for your exhausting enumeration of those problems.

Jason.org requires white space for empty arrays and objects while RFC 8259 does not (and I often see [] and {} in the wild).

A lot of packages de fact break the spec in other ways, such as ppl blatting python maps out rather than converting them to JSON so that the keys are quoted as ‘foo’ rather than “foo”. I’ve complained about this when trying to parse the stuff only to receive the response “it works for me so you must have a bug” from the pythonistas. This has happened in multiple projects.
