Re: [csswg-drafts] [css-shadow-parts] Unifying ::part() and ::--foo (#4900)

> And it would be selected as: `::--day.us-holiday`, the pseudo-class notation would be used to select custom state of the part, e.g. `::--day.us-holiday:--checked`.

That would require substantial changes to the selector grammar, and at that point, it might be easier to convert `::` (and `<ws>::`) into proper‑ish combinators.
