thats pretty much what happens when backend developers write UI, they mostly care about some ephemeral performance (hoping that their ui will get 1k RPS or something) while performance of existing tools (vue/react/svelte/remix/solid) is already absolutely enough even for heavy cases like high interval trading

This seems like a weird criticism. The motivation for people to switch to LiveView usually doesn't have much to do with performance. Instead it's about removing a whole class of work around client-server interaction. It offers the ability to have a server-powered UI be dynamic without any custom JS, to easily push content from the server to the client when something is updated, stuff like that.
