Pretty cool, I hadn't heard of Renarde and it looks promising. Around 8 years ago, I really wanted Aurelia to win the SPA wars but they're still pretty niche even though they've been growing lately. But honestly, after playing with everything over all these years, I still believe a server-side framework with minimal amounts of JS is ideal for most projects, especially all those internal corporate web apps but also for B2B stuff and even the average consumer-facing app. People say consumers are more demanding now, but how many developers are really working on something that caters to the most demanding consumers? Unless you need the most snazzy UX ever, just don't.

And honestly, using Rails or other server-side frameworks, you can get very far with way less effort than those expensive front-end teams by simply using Hotwire:

Sending down rendered HTML using Hotwire Turbo requires far less time, and HTML over the wire is in reality no heavier than sending down JSON. If you absolutely need a bit more interactivity on the front-end while avoiding a server roundtrip, it's easy to drop in little Stimulus JS controllers as-needed. From my journeys to and fro in the real world, I've seen most projects do not need more than that, and are arguably wasting budget trying to use heavier tools than that! For most sizeable projects, you can do more in Rails & Hotwire with fewer developers than a 6-person team using their favorite server side language and React. I'm not saying you have to use Ruby on Rails. I'm saying I wish the dev world would embrace this paradigm in whatever their favorite language/frameworks are.
