I migrated from vue 2 about 4 months ago seeking better typescript support and looking to move away from webpack. While I absolutely loved the simplicity and feel of svelte, I came to the same conclusion that it is not ready for a major production application yet. In a few years, I'm hoping vue setup scripts are as low friction as svelte or it may be time to switch over (they're close now, if you're using the latest macros, which may or may not be in beta still).
I've been writing operational apps with Svelte for over two years. I develop geospatial applications that make heavy use of WebGL. Haven't yet ran into any serious limitations. I keep things fairly simple and have been using tailwind the entire time. We had to fork a geospatial map framework (Cesium) to allow it to be loaded with Rollup.js as a simple javascript es6 module. But I wouldn't blame that on Svelte.
