So it sounds like the tradeoff here is that the generated bundle is more complicated/bigger. I'm not familiar with Svelt, but wondering about bundle size + debuggability.
At a certain size, yeah the bundle will be larger, but it would take a lot to get to that point. For pretty much anything you would do, the bundle will be much smaller. Especially if you use SvelteKit which is smarter about what is bundled and when it loads.
As for complexity, the generated Svelte code is extremely readable. Take a look at the generated JS tab in the repl: https://svelte.dev/repl
When I tried Svelte a while back (year or two ago) I had difficulty working with code in the debugger, couldn't seem to get source maps to work correctly, I wonder if it's fixed.
