Topic: Extensible Object Headers (Will L presents - refer published
slides)
Mo notes conflict regarding relay visibility of object payload metadata

Alan asks granularity of extension headers (per object/group/subgroup)
Metadata per object possibly required
5 issues of contention noted in slides
Victor asks for more clarity on use cases and examples, and negotition
hop by hop or per subscription
Will notes undesirable upstream messaging load with excessive
negotiation
Suhas listed secure objects extensions for end to end encryption and LOC
for media
He also proposed a scope parameter to add to the extension to identify
if relay needs to act on it or just blindly forward it
Magnus notes that last hop relay (mobile networks) may have enough info
and reason to filter extentions to final subscriber
Alan notes the need to define whether extension content is part of relay
cache key not (open issue)
Multiple comments on need to distinguish between relay oriented
extensions vs end-to-end extensions
Message integrity/immutabibility of extension list/content needs
support/definition
Will has noted all input and will continue discussion in list/PR and at
next interim
Martin makes formal request for specific input on extension use cases -
if you have them please send to list
