In UT it was possible, but to cut down on the netcode, they removed the extra traffic this required.
It didn't cost any extra bandwidth. Try viewing from someone else in a clientside demo in UT1 once, you'll only be able to view from his perspective for the time you saw him in the match. Also, there's a fat chance the view is messed up entirely anyway. (for example, it could be upside down, or the weapon mesh could be in front of the screen, more often both)
Even if you do a 3rd person view on your own character you'd probably not see more than you usually would.
The way it works now is a lot cleaner, but less practical for people that don't care much for cleanliness.
