I personally prefer it to being that way. UDP while is very simple from design point of view is actually very complicated to use if you plan to do something more than just send few packets. The issue is primarily, that you don't have a feedback loop that tells you the rate at which you should send the data. Also badly written applications that use UDP can create congestion collapse in a network (no congestion control/avoidance).
