For what? Doing a few "detection" calls during startup on a minimal emulator?

Because that is what it is mainly for, I used it when I still had a bunch of desktop powermacs. One would switch OF (the Apple firmware/bootloader) and kernel to serial, and then use a normal x86 videocard (and not some overpriced mac specific ATI card with an already old chipset), and then libx86 would initialize the videocard.

I'm not sure if it is still used much, since most bioses support the most basic functionality (init SATA, and I assume the video bios too) via 32-bit calls?

The fact that that page mentions alpha (which is essentially dead since before 2000) says enough.....
