I suggested one such idea (a diffing version of innerHTML) years ago to Mozilla. Ironically, the React team was against it and it fizzled out. In more ironic twists of events, someone eventually wrote a JS implementation of it: https://github.com/tbranyen/diffhtml/tree/master/packages/diffhtml https://github.com/tbranyen/diffhtml/tree/master/packages/di... and nowadays people are talking about HTML-based rendering engines again, making this idea somewhat relevant once more. To be fair to standards bodies, they have done some work. Element.append now exists to make hyperscripts a bit more straightforward, and a lot of reactivity semantics can be implemented on top of Proxy.
