Exactly! And that's why the choice in the UI is important. My understanding is previous versions of PF at least let your viewers know you offer salads. There's no (good) reason why the very minimum useful version of that can't be maintained. Comaps and OSMand for example are map applications, but they let me know when a given location has an associated Wikipedia article for example. They don't even need to implement something like a Wikipedia Viewer itself; just offer the links. Links are cheap, and are the foundation and backbone of both the internet and of any useful concept of a "fediverse".
