How is the progress going on the Stage 0 Proposal?

As per the title, what is the current progress for the Stage 0 Proposals for the immutable-data-structures? I know many people have been waiting to see how this "feature" progresses.

@sebmarkbage any updates?

It was presented last year at TC-39 but needed more experimental work and examples of it would be expected to be used before they're comfortable proceeding. It will likely be broken down into smaller pieces and iterated on such as maybe building on top of Typed Objects.

I'm echoing @trueadm here, @sebmarkbage Is there any update? Immutable data structures for JS seem imperative for it to progress as a language.
