You are being downvoted, but this is a good point. People would usually expect it to be a peer-to-peer mesh system without any supernodes.

The problem is that in the experience of the similar German "freifunk" project, which tried this with custom router firmware, this really doesn't scale well, even with a custom developed routing protocol (B.A.T.M.A.N). So many Freifunk communities are also choosing this supernode setup as a compromise between "full" mesh and good connectivity.
