I doubt you will find any enthusiasm for a dumbed-down INET type,
considering that IPv6 capability will be increasingly necessary in
the future.
As for unsigned ints, I have no objection to 'em in principle, but
in practice we have more than enough problems already deducing the
appropriate type for a numeric constant. Unless you've got a super
new solution to that set of problems, adding unsigned ints to the
numeric hierarchy is going to be unmanageable.
