A few "no-op" functions left ... let's remove them to get rid of unnecessary compat-stuff.

Might have missed some (?)

Looking good!

Side note...it would've been great if no formatting was done in this PR, made it a lot harder to review and ensure no logic/tests were touched 😅 .

I've gone ahead and merged the pre-commit PR into this (hence the complete rewrite of the history), so the files changed-count will go down drastically once that PR is merged in!

Closed in favor of #95
