Review comment:
There is nothing to decide because I created a PR to exactly discuss that.
This is merely a proof of concept to aid clients to properly terminate
connections.
I have considered introducing a constant for that. I will do.
WDYT in general? I'd aid clients and likely reverse proxies too.
Unfortunately, the draft for this header never made it to an official RFC.
