Plus requiering more knowledge, maintenence, and power supply for sometimes solar-powered setups. Think of a recent typical CN node like this [1], so no usb. The admins are not hackers. Also there are tens of thousands of existing and productively operating (partially 5-10-years-old) nodes that nobody wants to upgrade HW wise. It is really NOT as simple as it sounds to plug a $20 GPS !!!
