I have to say I really appreciate this! I was going down very similar lines just last week (I had installed Hammerspoon and was experimenting with some applescript hacks, but to no avail).

Just intercepting the actual scroll and inverting it is a really elegant solution (that doesn't require a relog) which is great.

This solves one of the two biggest gripes I had about MacOs - with the other being my inablility to "pin" my dock to one of my monitors, overriding the swap functionality. Thanks!
