## Summary
I mean I don't expect reviewers to go through every single change. It was painful enough to make all the changes myself, I had to write a script and regex the $*!+ out of the codebase to get this change through
## Test process
Tests pass. Searching through the codebase with regex queries to check for compliant strings.
