As far as I recall, it was initially not clear whether there is
consensus that the NAT-MIB is fatally flawed. (And the text that is
now in section 3.1 did not exist at that time in the current level of
detail as far as I recall.)

I suggest a consensus call is made by the chairs on this fundamental
question. If there is consensus that the NAT-MIB is fatally flawed
(and note that opinions of implementors in particular matter here),
then declaring the MIB module in RFC 4008 historic (e.g. marking RFC
4008 historic) and creating a new MIB module may indeed be the right
thing to do.
