I love svelte, and is what I reach for personally, but it's still early enough in its lifecycle that there's constant changes / new paradigms being introduced, especially if you include svelte-kit (originally it used sapper). If I had a team that had gone all in on Svelte I'd be bemoaning the need to upgrade recent code already.
