That's not true, it became available in all NSTextViews by default, although with a bit different look.

I’m not talking about Writing Tools but being able to run chat queries to do things, ala OmniFocus. I could see Yojimbo using features like “summarize all the docs in this folder” or “suggest the right tags for this”. It can’t take advantage of those built-in features.
