In general I like Svelte and SvelteKit although there's 3 problems I don't fully like:

1) The getter trap - if you forget to export hooks via getters you don't get reactivity and it's not easy to figure out (Svelte)

2) The async data fetching - for example fetching data async is currently coupled to views which it shouldn't be - was frustrating a lot (SvelteKit)

3) That reactivity system is not runtime only (Svelte)

I am also not a fan of adding these new things like remote functions - most of apps need multiple frontends and this coupling isn't needed. This will be fad same as GraphQL
