perhaps we should be more concerned that cgn (well, KLSN, kinda largish
scale nat, as nats really do not scale well) is the permanent death of
the end2end internet and the permanent establishment of walled gardens.
and yes, permanent.  i assure you that the providers have no plan to
remove them in your lifetime.  some carriers see klsn as integral to
their permanent walled garden ngn deployment.

ipv6 transition, if it happens, will take a long time.  during that
time, we need to give the users the ability to have real internet
despite the cgn disaster the carriers are going to create in their
desperation.

so, we either need to give them a better plan or give the users an out.
shared port addressing can do either/both.

of course it has drawbacks.  that's life in engineering and operations.
insane ivory tower idealism is what got us into this damned v4/v6
incompatibility mess in the first place, get over it.
