SG1 looked at this paper (P3960R0) in Croydon, March 2026. During the discussion P3963R0 (#2610) was brought up.

Poll: We would like EWG to consider P3963R0 and/or P3960R0, because
the motivation is compelling for concurrency and parallelism (we want this problem solved!)

Outcome: No objection to unanimous consent
