:anba noted that there is an outstanding spec issue with this. See Promise.Any (which also has an outstanding spec issue) for a discussion of a potential path forward.

The spec issue is on the agenda for TC39 the first week of June. It would be nice to land this in 78 for ESR, but 78 code freeze happens before TC39. I suppose we could land it now in 78, and uplift any spec changes to beta as a result of TC39, or else wait for TC39, and uplift both the pref flip and any spec changes to beta 78.

For MDN docs and devrel, can you please clarify if this is now indeed uplifted to Fx 78 or not? Thanks!
