I've been using Macs for decades and never had these issues personally. It seems like some people do literally rest their hands / arms on desk / notebook body while typing.
The "sharp edge syndrome" here to me seems to be a good thing then as it acts as a reminder for proper ergonomics / posture.
First Google AI search result on the topic:
"Never rest your wrists on your MacBook while typing. Instead, let your palms rest gently on the laptop body only when you pause. Hover your hands as you type. This prevents you from bending your wrists and protects the nerves in your carpal tunnel."
That also pretty much exactly mirrors the way we learned typing / posture at school in Austria.
