How can you be sure what's on other disks the code doesn't know about at the time it writes to the boot disk?
You could just say the EDD thing is only to be used in very simple configurations, but that's not half as useful as it could be - very simple configurations don't need EDD anyway.
If we encourage its use, so that it's basically assumed to work and boot processes use it by default, then people will be upset if things like adding another disk to a system just to read data off it cause the boot process to get confused.
