I hear you on the double, triple nat nightmare, I'm there myself. I'm
working on rolling out VRFs to solve that problem, still testing. The
nat complexities and bugs (nat translations losing their mind and
killing connectivity for important apps) are just too much for some of
our customers, users, etc to deal with. Some days it kills me that v6
is still not really viable, I keep asking providers where they're at
with it. Their most common complaint is that the operating systems
don't support it yet. They mention primarily Windows since that is what
is most implemented, not in the colo world but what the users have. I
suggested they offer a service that somehow translates (heh, shifting
the pain to them) v4 to v6 for their customers to move it along.

The problem is that you can't be sure that if you use RFC1918 today you

using that address, you really start to see the value in having world
wide unique, but not necessarily publically visible addressing.
That's what I meant by the 'as long as one is sure one isn't buying
trouble down the road' part. Having encountered problems with
overlapping address space many times in the past, I'm quite aware of
the pain, thanks.

RFC1918 was created for a reason, and it is used (and misused, we all
understand that) today by many network operators for a reason. It is
up to the architects and operators of networks to determine whether or
not they should make use of globally-unique addresses or RFC1918
addresses on a case-by-case basis; making use of RFC1918 addressing is
not an inherently stupid course of action, its appropriateness in any
given situation is entirely subjective.
