What exactly is getting in the way here? Standards do change. One standard (JSON) is not capable of representing all values from another standard (IEEE-754). Removing NANs and INFs would break floating point software everywhere, and a lot of hardware too. Adding support for them to JSON would be an enhancement, not a breakage. In my ignorance, that seems like a no-brainer.
Adding NANs and INFs to JSON will break virtually every software which reads JSON because many (most?) of existing standard-conforming implementations do not support them.
