My fear is that the second review will, more often than not, be a
"drive-by" review where X gave a positive review so Y just clicks
approve and merge---especially if the second review has to be from a
gatekeeper that may not be that much in touch with the code.

So I have no particular qualms with requiring two reviews, but I'd
rather not require a separate gatekeeper "super-review" and instead
allow 2 code owner reviews when there are 2 code owners.
