rel="in-reply-to" is deprecated

Nobody has claimed this yet.

The section on federated comments says "When marked up with h-entry and rel=in-reply-to and/or class=u-in-reply-to, your reply can show up as a comment on the original post." The rel="in-reply-to" property is deprecated and beginners may struggle to distinguish the difference between the class and rel implementations.

I was confused when seeing the rel value. It has not been adopted nearly as much as the in-reply-to class, which is documented extensively on the wiki (https://indieweb.org/reply) and in dozens of field examples.

@tantek said on Nov. 9th 2021 "It should be dropped from that completely or maybe given a warning to stop using it" in the IndieWeb Chat, recommending instead to "use u-in-reply-to instead on the actual h-entry reply" (cite: https://chat.indieweb.org/dev/2021-11-09#bottom).

Start with the federated comments section that mentions h-entry, rel="in-reply-to", and class="u-in-reply-to". Compare its wording with the reply guidance on the linked IndieWeb wiki and chat reference; done means the section no longer presents the deprecated rel property without the requested clarification.
