Should we use the same approach as native (iframe to login)? See Linear comment here

rainbowkit and wagmi are a couple of months old - at some point we can consider updating them (maybe after the initial release?)

Unfortunately this is blocked on the Webpack 5 update (ENG-114) because newer versions of wagmi have optional chaining (or maybe nullish coalescing?), which Webpack 5 can't handle directly without Babel. (Technically possible to add a Babel layer for it in Webpack 4, but we should probably just update already.)

My instinct is that embedding an iframe would introduce additional complexity (passing data between host and embedded page, tying nonce to "session" which we discussed we wanted to do for web, etc) which I'd like to avoid if possible. If we were to go with an iframe, I don't think landing would be the "right" place for it... but I guess since we're already using it for SIWE on native it isn't crazy.

I've been working on integrating SIWE on web directly, but if there's a strong case for iframe approach it would be good to get clarity asap to avoid wasted work.
