That's why I created SnapFire FSR (https://www.snapfirers.com), but many examples, to allow frontend devs to develop in their favorite framework (or mixture of). Write Tera templates, Web Components if you don't want to bring in frameworks like I tend to. Don't need to pay massive switching costs which, even with, AI not fun.
I found it much better to create and maintain web apps near the markup and language they originated from. You won't find me writing straight Rust for Web Apps unless I need to anymore.
I'm going to continue to work on this and switch all my leptos and svelte sites over.
