What a great project. For those who are wanting something similar for macOS, the Amethyst project is pretty great https://github.com/ianyh/Amethyst (meant to be more like Xmonad actually but still a tiling wm).
[Edit for context] I used Linux at home but was forced into a MacBook at work.
https://www.hammerspoon.org/docs/hs.application.html#launchO... was the primary method, though sometimes (such as teams) I had to get more creative.
That said, I believe https://github.com/szymonkaliski/hhtwm is quite popular, might be worth a shot if you want tiling.
