I feel like browsers would just cache these runtimes like they do with many js libraries so it wouldn't be a problem.

I am really excited at the prospect of writing my front and backend in a sane language like C# or kotlin.

Well yea, that's what I said. If WASM shared libs works, then we can cache runtimes, that's why I said it's the best solution. However shipping runtimes with user code, means it's basically not cache-able in a generic, multi-app sense.
