[csswg-drafts] [css-shadow-parts] ::part(foo)::part(bar) instead of forwarding? (#3841)

== [css-shadow-parts] ::part(foo)::part(bar) instead of forwarding? ==
I was going through the shadow parts spec, and it seems to me like a better alternative to complex part-forwarding micro-syntaxes (albeit maybe a bit more simplistic?) could be just to allow multiple `::part()` selectors.

So you would do `::part(filepicker)::part(button)` rather than `::part(filepicker-button)` or what not. Whether (or which) parts or a sub-component are exposed could still be controlled the same way `exportparts` works.

Seems to me the model would be much more consistent. Also, this is much easier (seems to me, at least, while I've been poking at this) implementation-wise, since you don't need to concatenate part names around to figure out if a part matches from a given tree. Stuff would just work.

Has this approach been considered?
