I was recently watching a talk about uv by one of the developers. One thing he said has really stayed with me after the talk - having tooling that works near-instantaneously unlocks whole new category of experiences. Inspired by that I gave Bun a try to see how modern front-end may look like without all the cruft, and it's just insane how much complexity you can shave off that way. For example, I would never imagine just bundling your whole project in a server handler. But it just works and if not for the lack of client auto refresh when files change (backend rebuilds just fine), I wouldn't even be able to notice the difference between that and dev server.
