Half-OT:

Svelte seems to be the pinnacle of the "bundling era" of frontend frameworks.

What do you think comes next?

XYZ-to-WASM?

Back the roots with (non-)bundlers like Skypack?

Anyone heard of next-gen experiments in that directions?

There is yew (https://github.com/yewstack/yew) which is a React inspired Rust framework that compiles to WASM.
