I'm certainly making no such assumption, but, yes, the other packet inspecting
things are vastly superior to NAT in at least the following ways:

1.	Deterministic, predictable troubleshooting
2.	They don't require heroic measures in the software to work around
	the damage introduced by your stateful inspection. Stateful
	inspection only breaks what it intends to break. NAT breaks all
	kinds of things whether the administrator wants to allow them
	or not.
