I don't think forks of clients with predetermined relays is the best way for users to discover relays. Users should pick their own relays, not just have them assigned by the client they first use.  

 Most are not going to do that though. How about a few popular public relays are default and the last one or two are randomized. What you think? 🤔 

 Every clients onboarding needs a relay explainer. The user must know how relays work and a good place to browse them.
