The extra content looks great; the only question I've got is about the location of the content. It's currently on the "how" page; but it seems to be more of a "what" question (which is born out by both the heading, and the shortlink added in beeware/beeware.github.io#839. Would it make sense to move this paragraph to the what/pr_review page?

Related to that - was the intention to update this content to include an explicit reference to the short links once they're available (which they now are)?

I've moved the updates to the what page, which is also the b/review-guide shortlink.

Only one shortlink is valid in this context, so I've replaced that. We could add a shortlink for "review-passing" or similar, but the context-aware link can't shortened, but it should still work in the what page (presuming how is inset of what, it should work across repo includes)
