Is there a particular proposal that you find interesting?

I checked this page lately, and it was kind of interesting, that the last landed proposal was in WG 2021-07-14. It looks like things are a bit slow lately.

I'm not sure about the priority, but it seems that Threads is certainly required for several applications.
And Relaxed SIMD and GC might be necessary too.
