It seems a bit like a baby-and-bathwater situation, honestly. It seems feasible to put in the standard something like that comments must be stripped out in the first pass and may never influence the interpretation of the non-commented JSON. A parser-implementation might choose to ignore that, but then it wouldn't be a standards-compliant JSON parser, in the same way it wouldn't be if it brazenly ignored any of the other sections of the standard.
