An expedient approach would be to allow selectors to penetrate the shadow
DOM by default and in a future spec revision add the ability for component
authors to opt out of this, along with introducing other features to
support custom styling.

The only argument I can think of against that is that the default is
"unsafe" for component authors, who will unexpectedly find themselves in a
deep hole later when they can't change anything their component without
breaking pages. But that's not too bad; it's certainly no worse than the
status quo, so at worst it's a missed opportunity.
