it does seem weird they would use that justification to remove the link. thought at first they might be consolidating for W3C-only resources, but there are non-W3C guides under the `Documentation` section (which is where I would guess the `ap-next` guide would also fit).
outside of clarifying underspecified pieces of the protocol, and highlighting some useful FEPs, how is the `ap-next` guide a "fork"?
