You can absolutely still use React/Polymer/other JS frameworks in that same manner, but you have to learn a little bit of coding boilerplate. I think one difference between lit-html and React/other JS frameworks is that lit-html knows which portions of its template are static, and can avoid reconciling static portions. This is the same optimization as what Svelte can do, but without the need to change your toolchain. Disclaimer: I work at Google, but on a completely unrelated team.
