There is a huge difference though: EFI is a widely used multivendor industry 
standard.  You are taking about something Xen-specific, and which in good Xen 
tradition isn't even documented, apparently (did we ever get documentation for 
the hypervisor ABI?)

Asking "why burden Xen with something Linux-specific" is a pretty extreme case 
of the tail wagging the dog.

That being said, before any code can be put anywhere, it needs to be written.  
We can argue where to put it later.  We went through this process with the EFI 
stub, too: a standalone implementation (efilinux) first.
