Just wanted to chime in here again to say that my implementation now also includes a rel=alternate link to the ActivityStreams JSON representation of the page.

e.g.

https://aaronparecki.com/2018/07/12/10/indieauth

<link rel="alternate" type="application/activity+json" 
      href="https://aaronparecki.com/2018/07/12/10/indieauth.as2" />

That brings this up to at least 3 implementations that support it, making it a good candidate to incorporate into the spec.
