There is such a thing as too much pretty. One can only stare into the face of Commander Shepard and friends so before being overwhelmed. Perhaps that's why BioWare left us this tiny slice of ugly — to keep us grounded.
I love the little shortcuts that go into developing a game on the scale of Mass Effect 3. Developers don't need to waste time on things like party-goers on a completely unreachable area. Who's going to look there, anyway?
If anything the area serves as a monument to all the folks that worked their arses off to make Mass Effect 3 look and play as well as it does; a way of saying "aren't you glad it doesn't look like this?"
