Agreed. As someone who primarily develops in python, I recently tried this exact same stack as a way of avoiding the inevitable (i.e. learning typescript). After dealing with the complexity of interleaving templates, overly complex information flows, etc. I copied some of the html from the jinja templates I created into a svelte project, added openapi-typescript to glue it all together, and moved on. While I am by no means a fan of typescript and modern web development, it is much easier build things given the extensive ecosystem. And if nothing else, the “frontend” is separate all of the core logic, which makes things easier to understand.
