BTW, that second sentence is a little goofy. Is it talking about
ADD/REMOVE being a matched pair? Or that there needs to be 8k of
metadata storage provided to each ADD/REMOVE call?

One thing I've noticed in writing changelogs and so forth is that
repetition can hurt understanding if the concepts aren't the same. Like
saying there is a "pair" of calls and a "pair" of pages when the fact
that both are pairs is a coincidence rather than an intentional and
important part of the design.
