Description

Now that RFC 6874 has matured and is a proposed standard, I'd like to reinstate the idea of implementing the support for IPv6 zone identifiers, e.g. for the proxy_pass directive. This would allow using IPv6 link-local upstreams.
In https://trac.nginx.org/nginx/ticket/623 this was rejected because the RFC was too young. Now as there are only for rejected errata and no movement for a while, I suggest revisiting this decision.

I would like to see this revisited as well.

Just in case it's not clear, the issues with RFC 6874 not disappeared, and this is not an RFC to be implemented in nginx. Upcoming RFC 6874bis, however, looks somewhat more promising than the original RFC 6874.
