I'd guess that a lot of macOS users don't care much since the pointer inputs (touchpads, magic trackpad) are really quite nice on Apple hardware. On the other hand, I definitely started using tiling WMs because the trackpads on my Linux laptops were always absolute garbage in the mid-2000s and early 2010s. The first time I used a Macbook touchpad I understood why so many people fell in love with those devices - especially back then, the touchpads felt magic compared to the crap being put out by every other PC manufacturer.

I personally use SizeUp instead of Moom, because I was used to using the keyboard and Moom's initial focus on a GUI threw me off. I only discovered later that Moom of course also supports shortcuts.

Some of my other additions:

- Karabiner-Elements, to swap Fn and Ctrl on the macbook's keyboard. I require Ctrl as my corner key!

- Witch, an alternative task switcher (alt-tab), which supports selecting individual app windows (macOS's distinction drives me nuts). Unfortunately it occasionally lags, so I'm iffy about it.

On all my linux systems, I have a separate Mod4 modifier that is exclusively used for key bindings that my window manager interprets.

On Mac, there's control, option/alt, and command, but various programs use various subsets of them, so none of them is available for me to completely commandeer.

Karabiner(-Elements) lets you convert a key to be a cmd-control-shift-option modifier, and I might just end up doing that, but whatever key you choose probably isn't going to be under my left thumb like my muscle memory wants.

For hammerspoon what I ended up doing is making modal keymaps, but modal keymaps are really different from how I handle it on my other systems, so it hasn't stuck yet.
