This relay seems useful, but only for people that utilize clients that take advantage of them. If your client doesn't allow you to generate feeds from a specific relay, then using this type relay won't be overly useful. Even if you removed all relays except this relay, to essentially only have a feed from this relay only, then you'd be hurting your decentralization and censorship resistance efforts. Being able to choose your own algorithm by creating a brand new feed is just another piece of the user choice puzzle and we'll hopefully see more clients adopt this path moving forward.
