Yeah I use Stimulus and Live View together as well. It is the right level of complexity, while I feel Svelte deals with a lot of stuff which is not even an issue when paired with LV. All you need is vanilla JS or a thin layer on top of it, not an entire framework. You will not have to write a lot of JS after all.

My production app has no more than 200 lines of JS, and I could probably get rid of a couple Stimulus controllers. Live View is that good. I also made a very hacky Stimulus-Live View hook adapter, so my Stimulus controller can send events directly to the LV process.

EDIT: Live View does not require you to run geo-distributed servers at all, unless you have bought into the fly.io kool aid a little too much. And it deals with disconnections beautifully. I didn't even have to do anything to support zero-downtime updates. The client loses connection to the WebSocket and reconnects to the new version, restores the state, all that out of the box automatically. What more do you need?
