But is the A20 gate being properly emulated? :) I know a verification engineer who left AMD because he was tired of dealing with the ancient testbench which checked the ancient hardware.

The browser should run in the hypervisor and provide a real hardware virtual machine. Provide both ARM and x86, one is emulated and one is real.

It's not. I haven't come across any software that relied on it.

Somewhat infamously, GRUB failed on Intel Macs (in 2006?) because it tried to use the A20 gate, and Apple refused to emulate it. It's fixed now, though.

Very old (as in pre-386, or even pre-286) DOS software, written for the PC and only the PC, might depend on it. If I remember correctly, archive.org has a whole section devoted to ancient DOS software, so you might find something in there.
