No. It is explicitly written that this specification is to define a neutral 
protocol between a boot loader and an operating system.

I know at least one more project which implements Multiboot: Etherboot. The 
support is partial, but it still supports Multiboot.

I talked about excluding the Multiboot Specification from GRUB with RMS a long 
time ago, because it was not really a part of GRUB, and it looked like a part 
of it, although it should be regarded as a generic specification, only 
because it was bundled with GRUB. And, he said that it was more convenient 
for people who would like to utilize GRUB to include the spec, and the spec 
was small enough to distribute with GRUB. His argument sounded good, so I 
decided to keep it.

But now it might be better to change my mind, since even _you_ misunderstand 
it. If you don't get it, how many people would understand?

Don't generalize your idea without asking. The spec is not limited to GRUB, 
and GRUB supports more protocols.
