Yes, mostly. They must not overwrite LinuxBIOS in memory. And there needs
to be a mechanism within linuxbios that allows to execute many of them.

It actually would be simpler, yes. But as far as I understood the common
discussion here, people prefer having a strict border between linuxbios
and it's payloads.

Functionally it is equivalent, yes.
