CSS Nesting

Should we start looking at adopting? Pros? Cons?

Can always postCSS back to flat syntax as a back fill?

Generally our syntax is pretty terse in ShadowDOM CSS. That said I can see this cleaning up some LightDOM styles for things like rh-navigation-secondary

I'm big on nesting, and think we can use it today in eleventy without issue, but I think we should avoid adding postcss transforms to shadow DOM (except for things like minification)

When browsers ship (soon!) We can just add a stylint rule to auto-fix flat->nested

I agree, I don't think it's even necessary in our shadowDOM CSS as it stands. No complex selectors really necessary.

Definitely see it as a bonus for LightDOM though.
