I have to agree with the conservative people here that NAT is an added
layer of protection against configuration errors. I have once seen a
case where an accidental "allow all" was inserted into a stateful
packet filter, which caused a server with an official IP address that
was supposed to be "protected" by that packet filter to be r00ted in
no time. Had this server behind a NAT gateway with only tcp/80 DNATted
to the site local IP address of the server, this configuration error
wouldn't have been remotely as bad.
