Dan Druta raised the question of priorities earlier on the mailing list. The thread starts:
  https://mailarchive.ietf.org/arch/msg/webpush/7ltW-kU9katoRX6J0hlv-QAFplM

There's also a related issue open on our github:
  https://github.com/unicorn-wg/webpush-protocol/issues/28
which references - https://tools.ietf.org/html/draft-thomson-http-nice-02 - as an option to explore.

It would be helpful to first clarify use cases and requirements as Dan concluded in the earlier
thread?
