Thanks! 1) I know basically nothing about patents, grants and licenses, so I can't comment there. 2) There are transforms to help minify lit-html templates, like https://github.com/asyncLiz/rollup-plugin-minify-html-literals https://github.com/asyncLiz/rollup-plugin-minify-html-litera... . See https://github.com/web-padawan/awesome-lit-html https://github.com/web-padawan/awesome-lit-html for more 3) lit-html requires objects with state and behaviors. Seems a perfect fit for classes. We usually get feedback that the source is very readable. I don't think there's any tension between the implementation using classes and the API surface being functional.
