Agreed, and if you want to write tools that are conformant with both specs, you really don't have a choice. The RFC pretty much spells out this point: "JSON parsing libraries have been observed to differ as to whether or not they make the ordering of object members visible to calling software. Implementations whose behavior does not depend on member ordering will be interoperable in the sense that they will not be affected by these differences." (This kind of text is why I prefer the ECMA document -- it's clearly written to be a normative standard, rather than as a field-report and Request for Comments.)
