The fact that it "deserves" its own page is precisely my point. "It has more features" -> "it takes more implementation work than just replacing all addresses". Even ignoring the base work of making things dual-stack you have fundamental rewrites of base assumptions about addresses to take into account.
Actually, ipv6 takes less implementation work from a network operations standpoint. Every site gets a fixed size network, every building gets a fixed size network, every vlan gets a fixed size network. No more IP budgeting and wrangling nabout justifying IP allocations. "Is that worthy of a /18 or should it be a /20?" That's all gone. Every vlan with people gets a /64 and your router interface to them is fe80::1. Turn on SLAAC and let it run. No more NAT pools and rules. It's great!
