Just my personal opinion: I love svelte for small projects but the whole runes rewrite just feels so much less ergonomic. A step in the direction away from the simplicity that drew me to svelte in the first place.
That said, there is backwards compatibility with the older syntax, so this isn’t a dealbreaker, and the team does a good job of explaining the reasons behind their selected design patterns.
(Interestingly, I’ve felt the opposite with react lately - they’ve been making the dx simpler).
