HTTP docs talk about defacto standard, but seems to be a mismatch compared to mozilla

The following is taken from https://quarkus.io/guides/http-reference#reverse-proxy:

To consider only de-facto standard header (Forwarded header), please include...

I understand that to mean that the header named "Forwarded" is the de-facto standard.

This seems to contradict https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Forwarded, which says:

The alternative and de-facto standard versions of this header are the X-Forwarded-For, X-Forwarded-Host and X-Forwarded-Proto headers.

If you follow the link, for example for "X-Forwarded-For" it then says:

The X-Forwarded-For (XFF) header is a de-facto standard header

I think the Quarkus docs are wrong - agreed?

Hmm. Reading more on Mozilla, it also says "X-Forwarded-For" is "Non-standard. Check cross-browser support before using."
