It is nor up to us. We want the best censorship resistance available, and that requires a large overlay network, in this case the best is Mainline DHT, but ANY overlay network you can think of uses ed25519 keys, not secp256k1.

So right out of the gate, we can't use npubs to represent identities, at best we can use a sub key to use Nostr relays as free infrastructure, but without real interop because Nostr clients don't know that these  sub keys are all part of one identity delegated to by an ed25519. 

would that have been "enhancing Nostr"? if so, feel free to do just that right now. If that is what "other folks on Nostr bringing DHT" means, perfect. Let everyonr have a sovereign ed25519 key. And call it Nost if that makes you happier.
