It's more an issue of ESD protection being kinda tricky on DIY boards due to the need to stick with THT parts. When you're building a $200-$300 keeb, a $0.05 diode doesn't really all that much price-wise. ESD protection diodes also don't really solve the problem. They are intended for short-duration high-voltage low-current spikes, not long-duration low-voltage high-current ones. Definitely better than nothing, though!
