TC39 seems to be failing at many things for the past 10 years.

Browsers have said that they are unwilling to ship any new cancelation mechanisms given that AbortSignal already exists, so we can't ship a different CancelToken. But I think there's a path to standardizing a subset of the existing AbortSignal machinery [1].
(I am on TC39 and while this isn't my highest priority I did bring the topic for discussion at the last meeting [2], and there was support from the rest of committee.)
