Hm. Can we be more descriptive here? Maybe something like "Support for
read-your-writes query patterns on standbys via the new..."

Per commits 1a562a2661b and e527bf17d04, I think we're just calling it
"WAIT" and not "WAIT FOR".

IMHO this makes it sound like users will be able to choose the priority of
each individual table, when we actually are just giving them a handful of
coarse controls. I think we ought to emphasize the scoring system instead.
In theory, most users shouldn't need to adjust anything and the
prioritization will "Just Work" for them.
