@Jack-Works recently and @robpalme previously suggested that JSON modules be frozen. We previously concluded that they would not be frozen.

However, in the context of JSON modules potentially standardized by TC39, maybe we could reconsider, and freeze JSON modules this time. I would be OK either way, personally.

The PR for JSON modules includes them as un-frozen. This wouldn't necessary prohibit a host/implementation from going around and freezing it (depending on the metaphysics of spec reading), but it'd be nice to really have a solid, cross-environment decision one way or another.

I want to argue that this is something that we can iterate on during Stage 2 and need to decide on before Stage 3.
