Just next to the proprietary port is a USB-C one. You can buy a good USB-C ethernet adaptor for less than half the price of the Lenovo dongle.

My ideal would be a non-proprietary, smaller native Ethernet connection capable of 10GbE.

The adapter still has to adapt. That requires power, adds cost, and adds negligible-but-non-zero latency. I don't love the proprietary port being proprietary, but the fact remains it is native Ethernet with no caveats.

They are getting rather small[0] and not-crazy-power-hungry these days!

And if we're being honest: is there really that much difference latency-wise between Ethernet -> NIC -> USB -> CPU and Ethernet -> NIC -> PCIe -> CPU?
