Reviewer comments:
This PR covers questions asked during Auth48 which aren't pure copyediting, but seem to have a straightforward single-location fix. Individual commits, so it's easy to pull one out if someone disagrees.
In , the RFC Editor asks:
Either A or B is better, but I have no preference.
Fixed in , but GitHub won't automatically close until it hits .
