If we go for a model where each of us has our own personal relays, "DVM feed builders" might offer a better user experience for most people.

If it's seamless to the point where a brand new user would have zero friction, then sure, have at it. Otherwise this sounds like it would be very confusing. UX is incredibly important. The tech can be cool as fuck, but cool and better tech doesn't always win.
Agree
Then the DVM is the centralizing bottleneck?
