@grishka I understand. The Murmurations thing is a mere idea I want feedback on.
It is nothing more than a more cleaned-up well-structured document template as-a-profile + having them auto-aggregate so there's no manual work involved in bringing things together. Not per instance, but per app / codebase.
Note, I like your idea. Murmurations besides JSON-LD uses JSON Schema for validation, which *might* be used here too. Though that does not cover "yes but only if they follow you".
Just musing.
