Lit-html is so fast and cheap, batched rendering isn't really useful.

I will sometimes do a little trickery in my setters to prevent pointless server round-trips though.

The general rule of thumb with lit-html is "meh, just render. It's just a template clone, and pretty much free".

There's no need to miss css selectors, they work just fine. That's the advantage of avoiding shadow dom.
