Thought the same, then tried a Corne-ish Zen and … I’ve been on a strange path from normal keyboard to split kbd to Ergodox to Moonlander (so more and more) down to Corne-ish Zen (3x6) and my hands/wrist thank me daily. Even today I edited my keymap https://github.com/Utopiah/zmk-config-zen-2/blob/main/config/corneish_zen.keymap thinking “Wow… so much keys left still, I could do with less”.
