One advantage of SIWF over SIWE is that you don’t need to have 3+ different buttons / flows corresponding to different wallet providers 

Just scan a QR code, and you're authenticated

I hope that as SIWF extends to other clients, the simplicity of having a single interface is maintained

Yep authkit and the relay etc could all be run by other clients though currently to do it they need to provide a signature from the custody address which is why no one outside Warpcast bothers right now (no other client has enough active users where they control the custody address or the custody address isn’t Warpcast )

Developer 🤓 build, develop and operate Farcaster solutions @ dtech.vision also love tech, decentralization, fitness and oldschool rap 😎

It will yes, but by then it will still be the same QR (hopefully) and the deeplink will just open in the app the user has (please)

This will change over time though, but yeah the consolidation around one wallet app has been good for UX (and dev x)
