@JaceRockman Do you want me to hold off merging this and work on the corresponding changes in your branch?

I originally tackled this based on your ask in Slack... and albeit it turned from a single-commit fix that took about an hour to to something that ended up being much larger to address the good feedback and some other related changes that were not fix-specific.

Yeah, I see some of your comments on my PR, I can fix those there if we just want to make all of these changes as one PR.

I'm inclined to merge this one, and then rebase #800 on this work. This one is ready to go and is a subset of that one, so that seems like the smoothest path.

Closed in favor of #800
