Even though that might seem arbitrary, it's the only way to prevent anyone adding their own configuration for those pins, which would be a mess to maintain and use. It's even more true since that sort of thing is exactly where the overlays shine. So, I'm ok with adding the uart4, but the uart2 should go.
