The general trend for laptops seems to be going thin and light at the expense of connectivity (like Ethernet). Would you be interested in a laptop that went the other way and included both a 1000base-T RJ45 and a SFP+ or QSFP+ cage?

No, just lots of USB3 ports. Can do everything else over USB and it's thinner, lighter, safer, & needs fewer drivers.

USB is safer than Ethernet? It needs kernel drivers etc, and a USB device can pretend to be all kinds of nastiness. Meanwhile, a LAN is a LAN and there's nothing else it can do.

Yes. Onboard/PCIe ethernet likely has bus-mastering capabilities, integration with ME, boot-from-LAN functionality, etc. USB ethernet is purely a standardized protocol over USB.

In an ideal world the only real hw driver is the USB host controller, and everything else is just protocols (that could be implemented purely in isolated userspace contexts with no mmio/dma/etc programming).

"Pretend to be all kinds of nastiness" is a flaw in OS handling of USB devices (automatically assigning a role/privilege to a newly connected device) rather than any inherent problem with USB.

In that case ME, boot-from-LAN, etc are OS/BIOS/mobo failures rather than inherent problems with Ethernet. And bus mastering is perfectly safe if you have proper memory protection at the physical address level

The failure is more fundamental - it's a failure in trust. User should not have to trust that fishy stuff like that isn't happening. The hardware topology should make it obvious & minimize the amount of hw that has to be at the root of trust.
