What's the plan for JSON.parseImmutable after Records & Tuples withdrawal?

[LiviaMedeiros]

Since the Records & Tuples proposal was withdrawn at the TC39 plenary on 14 April 2025 and the Composites proposal covers many of the same use cases, i'm curious about the future of JSON.parseImmutable. Should this proposal be archived alongside Records & Tuples, is there a plan to adapt it using Composite, or should it remain on hold until a proposal with immutable structures reaches Stage 3?

One option is that the API returns regular objects, no different to Object.freeze but with the potential efficiency compared to JSON.parse and then doing a manual traversal to freeze.

Another option would be to adapt it to use Composite, though we'd have to wait to see how that proposal evolves.
