"We" forgot to ask if all the stakeholders wanted it solved. Most
self-styled "enterprise" operators don't: they want a major control
point at the network border. Deliberately breaking end to end makes
that control more certain. Which is why they deployed IPv4 NAT boxen
long before address scarcity became an impactful issue.
