Since nobody has experience with LSN, that's a pretty easy statement to make.

However, given the tech. support costs of single-layer NAT and the number of
support calls I've seen from other less disruptive maintenance actions at various
providers where I have worked, I think that in terms of applicable related
experience available, yes, this is backed by experience.

ROFL... John has already made it clear that his usage profile is particularly
NAT friendly compared to the average user.

Uh, no.  Interesting how the wilful ignorance around NAT and IPv6
is both delaying IPv6 transition and being used as an excuse to make
things even worse for customers in the future.

I guess that depends on whose choice you are interested in preserving.
