I still see this as an issue, tbh. This has been discussed before, but in essence implementing referral fees in this way reduces the cost for registration by X% for bulk ENS buyers, which is the group that the fees are designed to keep in check in the first place. In that way, referral fees work a little different in ENS than something like Zora, for example, since in ENS, the sole purpose of the fee is resisting domain parking.
Previous discussion for context:
An additional point I’d add is that while I think finding ways to incentivize the spread of ENS names is important, I’m not sure it would be healthy for the ecosystem to incentivize selling .eth names so directly at this point. Reason being, I think subdomain adoption is much more important to the long term success of ENS, and adding a direct profit motive into the protocol for .eth names could work against that effort and distract from the new world Name Wrapper could usher in.
Curious to hear if @nick.eth has changed his views on this since that discussion earlier this year.
The other improvements are great though! Good work!
