As someone that into mech keyboard hobby, I can say that’s still perceivable for average user as you still retain the familiar “qwerty” layout.
Look up stenograph keyboard. They have lesser keys but allows someone to write higher wpm and programmable though I don’t think they would fit for average office workload (unless you types a lot).
Especially when they have luxury of lubed switches, foam, dampeners/stabilizers, custom case material (that keeb def. Custom one).
