whatever DOM does quickly becomes a compat constraint on all future
decisions
(was the comma omitted on purpose? ;-) )
This also means that if there is a delta between the agreement and the
implementation, we'll have yet another de facto standard. There are two
ways in which this can happen:
* misunderstanding of intent
* misexpression of (even perfectly-)understood intent.
1) What should tc39 do quickly, to unblock the DOM's need for promises
and avoid a design fork?
I apologize for being annoyingly insistent with this, but: tests.
An unwanted de facto standard is a de facto design fork.
I believe that to a large extent, the risk of both misunderstanding of
intent and misexpression understood intent would be largely reduced by a
test suite.
The people who (will) implement this feature aren't necessarily the ones
involved in this, sometimes very subtle, discussion. I believe fewer
information would be lost if the latters formalized their agreement in
tests for the formers to implement against.
