Having IPv4 just for your public facing servers is a small expense, and within the private network you can still use private IPv4. The biggest pressure is to allow your servers to call out into the internet without an IPv4 address or a NAT. That's pressure on APIs, SaaS services consumed by backend servers, update servers, etc.

Maybe that's enough to remove the friction around IPv6 and make it "just work" to the point that everyone just keeps it on. Or maybe it doesn't and we get a divide where everything consumed by machines moves to IPv6 while content consumed by humans keeps preferring IPv4.
