Any update on this?

Hi @lin72h here are the notes and slides for R&T from the last TC39 plenary (Nov 2022). One of the current concerns is from implementers on the technical challenges of implementing and supporting R&T, and a request to explore if there are ways to reduce the implementation cost while meeting the same core goals.

Thanks for the links. Really looking forward for R&T coming in 2023
