Single file components like .svelte and .vue are nice at first glance. But I want typescript, eslint and prettier understand my code natively and not wrapped in custom syntax and smushed into one file that every tooling now has to support.

Maybe it's finally time for someone to standardize this - even if just pointing at what vue & svelte already do - so every tooling can go ahead and support amalgams of filetypes in a single file for any framework that wants to work like this.

It's a wonder how react managed to force their jsx and angular forced annotations into typescript just to get a good typescript experience out of the box.
