I recently went on quite a rabbit hole regarding the .well-known directory, and wrote about it.

    You are right that it does feel a little roundabout. My understanding is that webfinger converts from the username to the user profile url and image. This is useful during federation, and for generic fedi/activitypub clients because different Fedi software maps usernames and profiles differently.

    For example, [email protected] will reside at lemmy.instance/u/user, while user @mastodon.instance will reside at mastodon.instance/user.

    Fom some poking around, it seems that Lemmy does not properly support sending the profile image on Webfinger because I wasn’t able to do it using the rel parameters that are mentioned in the spec.
