On: PCI-Sig Releases 256GBps PCIe 6.0 X16 Spec

It's not just segmentation. Laptop buyers are not going to pay for 64 lanes. A regular Intel SKU of the 12th generation has 28 PCIe 4.0/5.0 lanes. A Xeon has 64, does not have 5.0, and costs way more, partly because it has 4189 pins on the bottom, which is insane.

Based on page 131 of this, it looks like a PCIe lane only uses up six pins.

I'd worry about the die space and the power use but not the pin use.
