My purpose was to make sure people understand what words like "done" and
"frozen" mean. Let's see, the API changed among minor things thus:

  FutureResolver -> PromiseResolver
    .accept -> .fulfill
  Future -> Promise
    .done -> ???
  + Promise.fulfill
  + Promise.resolve
  + Promise.reject

Plus behavioral changes. When I tell somebody a specification I work on
is "done" or tell them an API is "frozen" then they can be sure that it
is no longer possible to make changes of this magnitude. To you and Tab
Atkins the words obviously mean something else; it's good to have that
on record.

You might also want to clarify what Tab Atkins meant when he said that
"Promises aren't going to be a W3C deliverable anyway" in the message
above, considering your efforts to get "Promises" into W3C deliverables.
