Thanks again @etseidl -- I think the code in this PR looks great.
Also, I know it was more work, but breaking them up into multiple PRs has made reviewing it much easier (though I admit it is still taking pretty long)

There will be a small conflict here with #6450. I couldn't use the new API for the page indexes until the behavior change was dealt with.

I verified that these tests have already been ported to the reader module:
