Call for Adoption: Extensible Prioritization Scheme for HTTP

Hello HTTPbis,

During our IETF 106 meetings, we received updates from the design team for updating HTTP's priority hinting mechanism, with the goals of defining priorities for HTTP/3 and allowing this scheme to be backported to HTTP/2.

The output of the design team is documented in this draft: https://tools.ietf.org/html/draft-kazuho-httpbis-priority-04

This draft defines:
- A SETTINGS parameter to disable the HTTP/2 priority mechanism
- Two priority values, urgency (0-7), and incremental (boolean)
- Mechanisms to communicate these priority values using headers and frames

This email begins a call for Working Group adoption of this draft. Note that adoption indicates that we, as a working group, want to use draft-kazuho-httpbis-priority as a basis for the definition of priorities for HTTP/3. There is still ongoing discussion that will continue, specifically around the mechanism for end-to-end and hop-by-hop signaling.

This call will end on Friday, December 6. Please reply to this email and indicate whether or not you believe we should adopt this document!

Best,
Tommy & Mark
