I'm whole-heartedly for this! This ties nicely to my b4 work where I'd like to be able to identify code-review trailers sent for a specific patch, even if that patch itself is not on lore. For example, this could be a patch that is part of a pull-request on a git forge, but we'd still like to be able to collect and find code-review trailers for it when a maintainer applies it. Currently, I am using the following approach: | Reviewed-by: Some Developer <some.dev@xxxxxxxxxxx> | --- | for-patch-id: abcd...1234 Then I can query 'nq:"for-patch-id: abcd...1234"', but this is probably much more heavy than if I could provide this in a custom header: | X-For-Patch-ID: abcd...1234 and query for "xforpatchid:abcd...1234" > I'm trying to avoid supporting sortable numeric values for this, > since supporting them will problems if columns get repurposed > with admins changing their minds.
