lol well look at that. that's neat. seems a bit roundabout. How do you know the resource though? so you request the user information with the resource query param, but that means you already know the user, which means you likely got it from somewhere else right? if you got it from somewhere else, you likely have the ability to get the profile information from that location rather than requesting information twice. or am I thinking about this completely wrong?
for example, I completely understand the chatgpt plugin and change password ones, but this one doesn't really make sense to me, since you have to know information before hitting 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, user@lemmy.instance 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
relparameters that are mentioned in the spec.
