Sure we can use that as a starting point. The basic policy that we
discussed in the working group was that any public API change should be
advertised on the developer mailing list. If no concerns are raised after
several days, then the change could proceed. If concerns were raised, then
discussion could start on the mailing list and continue in the next meeting
of the API working group if necessary.

The Traffic Server policy includes a few other concrete details which we
did not discuss. I'll quote it here to make things easy:

Due to the importance of getting API right, there is a required review

I think this is pretty good as-is; replace "Github Issue or PR" with "JIRA
issue or ReviewBoard patch", and remove the portion about 'experimental.h'
and what follows.
