Slower - not really now Rust client web frameworks have improved. Don't have refs handy, but Leptos, Dioxus etc are on a par with Solid.

Larger bundle sizes - yes that's still true.

And not all GUIs are web GUIs, so WASM isn't the whole story.

Yeah played with some Leptos wasm and i believe something simple like their book tutorial was like 335kb or so. Not that shocking and for me personally totally acceptable. I do wish browsers would ship with their std lib for wasm. So wasm is can become more competitive on bundle sizes with Javascript which has its std lib shipped with browsers.

Yeah also note that 335kb of wasm isn't as bad as 335kb of javascript.

Its true that large javascript bundles are bad because big files take longer to download. But the arguably larger problem is that parsing javascript is really slow. This isn't as big an issue with wasm - the browser can parse wasm many times faster than it parses javascript. If I recall correctly, wasm parsing speed is about on par with the speed of parsing pngs.

So having 335kb of wasm is similar to having a 335kb image on your landing page. Its not ideal, but its not a showstopper.
