@crccheck I think this is a WIP. I'm inclined to close it to keep the open PRs minimal until there's more of a direction for the work that requires discussion/review.

I think there's some value in asserting how many quietus Django sees vs how many queries the toolbar sees. I think both functionalities use the same underlying data structure, which makes this additional assertion not very useful. Or maybe I'm missing something?

@crccheck I'm going to close this. If you feel like this is important, please let us know why and we can reopen it.

oh sorry, I only opened it to see if CI would run it. I figured out how a minimal command to get tests to run locally since then and I thought draft PRs wouldn't show up

FYI @matthiask there's an issue where Django's queries actually don't match Debug Toolbar #1791 I was trying to recreate
