If I build my recipe sharing app for the Fediverse (see fediverse-ideas 44), I would not expect Mastodon to have to change in order to support it.
I also firmly believe that: "Helge is able to create a recipe sharing app for your network that interoperates in a sensible way" is a criteria for if your network is good.
If your social network is specifically targeted at recipes, use "making animal sounds" instead. Being able to moo is important too.
