The other outcomes are a redesign and more configurability plus a bunch of new features. It wasn't really an apples to apples comparison. The non-iFrame version was more of a 1.1, where the new thing we are building is a 2.0. Based on some other projects, I do suspect it would have gone faster if we built it on the old stack.

The development team made the choice to go with Remix (well, the tech lead and VP of engineering). No one had used this tech before. We have subsequently talked about whether it would have been better to do the whole thing with Rails + Hotwire. We have been using this approach elsewhere in our stack, and it seems to be a lot conceptually simpler than rendering JS server side and then hydrating it.
