I went down this rabbit hole and I now:

- use 30 keys

- control the mouse from my keyboard

- never have to move my palms in the slightest all day

- get far more control and (Emacs) keybindings

It was a very painful process though deciding on my custom key layout. I would make myself re-learn new layouts on an daily or hourly basis for 6 months until I was satisfied.

I have a Moonlander but my long term plan is to move to Tightyl: https://www.reddit.com/r/MechanicalKeyboards/comments/glfyki...
