I'm trying to steer the user toward the way to solve their problem,
which is to use a device tree. I expect less than 1 QEMU user in 100

I'm not sure what you mean here -- we have two boot methods and
only DTB handles large RAM sizes. Or do you mean machines with eg
flash where you could boot by putting a bootloader in flash?
