(Please consider this as more of a grenade lobbed into the conversation
rather than a carefully thought out proposal...)

My inclination is to say that it's not really the responsibility
of QEMU to define either -- we provide emulated models of hardware,
and it's up to the user or the management layer or the provider
of the firmware to specify what guest code they want to run and how
it needs to run on that emulated hardware...

Where the QEMU upstream itself is providing firmware blobs
(in tarballs etc) it's probably our job to specify how they work,
but if the firmware is compiled and provided by the distro (as eg happens
for Arm UEFI blobs at the moment) then I don't see how upstream QEMU
can reliably define how that firmware needs to be loaded.
