Okay, so this is something that was implemented for WordPressMU, but  
it's 1) not fully implemented, as the {blogid} in her example is not  
present, and 2) it's not necessary for vanilla single-user WordPress.

I understand its usefulness for MU, but is there any reason for it to  
be here in regular WordPress?  Since there is a code difference here  
anyway (compared to MU), why not just remove this redundancy entirely?

That seems far simpler (and less bug-prone) than adding code to  
distinguish between two options -- one of which isn't used!  :)
