May I ask you how did you find the process of programming a Shopify app using Svelte? I have some experience with Svelte and am currently in process of starting development of a new Shopify app, but I basically decided to go with React as they have a lot of documentation and libraries (Polaris, AppBridge) available for it, while on Svelte I would have to do everything from scratch (or at least that's how I understood it from their docs)
EDIT: after reading your comment one more time, I assume you've used Svelte only for a small part of the app, not the app as a whole?
We are using next.js for the admin interface of the app. Works great with Polaris and AppBridge. Svelte is only used for the widget we are providing to the merchants.
