The bios memtest86+ is still these days installed to /boot but there hasn't been a menu entry for it for a very long time; in fact maybe it was only ever on netintall or dvd images? I can't remember that far back :P I guess the gotcha with a single boot image, is it can be difficult to boot BIOS and UEFI from a USB stick (treated by firmware as a hard drive) and from optical. We're doing this today with the common Fedora desktop and server ISO images, created by xorriso which has an ISO hybrid option that bakes into the ISO 9660 image, two El Torito images. One for UEFI and one for BIOS. That's because, hilariously, natively booting ISO 9660 or UDF is not a thing that was added to the UEFI spec. But if this image works consistently, and we don't sneeze, it should be OK? What's this...
