I'm not the OP, but I find working with SvelteKit to be an extremely positive experience. It has completely re-sparked my love of programming.
For the older people here on HN, maybe you can relate to this: I remember back in the late 90s when the LAMP stack first became a thing. We can poopoo it now, but it's really easy to underestimate the effect that stack had on soooo many developers. Going from static HTML to a relatively easy, accessible, and CHEAP way for any poor developer/college student like myself to generate dynamic content felt nothing short of magical. Suddenly it was possible to create just about anything you could imagine.
There have been many improvements on ways to build web apps since those days, but I have never had that feeling of pure magic since. Until SvelteKit. It is a leap forward, IMO. The framework clicks for me, front end code, server side code, all in the same app, and in a way that from my view could not be easier to understand. It for me is that next leap forward.
