> 1 × USB 1.1 controller and PHY, with host and device support

Sure, after integrating USB 2.0 HS or 1Gb-Ethernet the pico2-board will cost more than $5. So, integrated high-speed interfacing with PC was not a nice-to-have option (for special chip flavor)?

GigE is actually PAM-4 at ~250 MBaud.

1.25 Gbps would be needed for low-pin-count SGMII interface to a PHY chip.
