It also has barely seen any activity in years. It is going nowhere. The TC39 committee is utterly dysfunctional and anti-progress, and will not let any this or any other new syntax into JavaScript. Records and tuples has just been killed, despite being cited in surveys as a major missing feature[1]. Pattern matching is stuck in stage 1 and hasn't been presented since 2022. Ditto for type annotations and a million other things.

Our only hope is if TypeScript finally gives up on the broken TC39 process and starts to implement its own syntax enhancements again.
