There's just a lot more experience with UDP than there is with some other non-TCP protocols. Engineers have been more motivated to deal with it than they have with, say, SCTP. But anyway, firewalls solve a different problem from NAT. NAT has incidentally been used as a policy device but a firewall really is a policy device. So, while it might be reasonable to say "I need to figure out how to get across a NAT," it would also be reasonable to say "I need to figure out how to get across a firewall without violating access policy." You definitely do not want to design a mechanism that enables policy violation.
