Isn't there a recommendation not to use the X-
prefix for any new headers?
There is, but there is a clear existing convention for using the X- prefix
in Wikimedia-specific headers, so I think local consistency trumps the IETF
recommendation. We currently have X-Analytics, X-Trusted-Proxy,
X-Wikimedia-Security-Audit, X-Pass-Stream, X-Carrier, X-Carrier-Meta,
X-CDIS, X-Subdomain,
X-Orig-Cookie, X-MediaWiki-Original, X-WMF-NOCOOKIES, X-ZeroTLS,
X-Forwarded-By, X-CS2, and X-Subdomain. And this is not an exhaustive list.
