Our desktop app builder is also built on Svelte (not SvelteKit).
I agree with pretty much everything in this article. I wouldn't put "Reactive declarations and statements" in the "Ugly" section though. They are definitely a bit tougher to fully grok than the rest of Svelte (Svelte is incredibly easy to learn compared to other frameworks) but once you learn how they work they are incredibly powerful and concise.
I also feel like "Svelte’s lack of protagonism" is a bit off the mark. Rich Harris is a great communicator and tends to be pretty public but the focus is more on community. Svelte Society's Youtube channel [2] does a 1 hour long "This week in Svelte" video every week and it is all killer content with no filler.
