@p @NonPlayableClown @toiletpaper The `application/ld+json; profile="https://www.w3.org/ns/activitystreams" ` thing?
I feel like that's just typical W3C, it doesn't even makes sense.

But well I'm the kind of bastard who thinks it should just have been something like XML with stylesheets so it renders somewhat sanely in browsers, so URLs no matter what kind of headers you pass still uniquely identity a ressource.

(For example https://hacktivis.me/feed.atom works like this)
