1. I think there should be a single link to the whole "URI" doc instead of many. WDYT?
2. https://jc-verse.github.io/mdn-graph/warnings reports a few other unreachable pages. Not sure if you want to add them too.
   • /en-us/web/http/browser_detection_using_the_user_agent
   • /en-us/web/http/configuring_servers_for_ogg_media
   • /en-us/web/http/cross-origin_resource_policy
   • The landing pages of Headers/, Methods/, and Status/
   • /en-us/web/http/network_error_logging
   • /en-us/web/http/proxy_servers_and_tunneling

I'll take a look how this appears, but I think you are probably right.

https://jc-verse.github.io/mdn-graph/warnings reports a few other unreachable pages. Not sure if you want to add them too.

Very convenient, ty. I think these should be in there as long as they live in this directory (Ogg guide may be a candidate to be moved out to https://developer.mozilla.org/en-US/docs/Web/Media but not for now.)
