Since Github PRs don't support stacked diffs, @topperc and I decided that it would make sense for me to submit a multi-commit PR. When I get the LGTM, I'll manually apply each commit to the main branch and close this without squashing and merging. 
Do you agree that this makes sense? If you do, I'll add some tests to the commit.
