Speaking with my Enterprise Day Job hat on...
I started doing analytics on IPv6 client support regarding a (currently
IPv4-only) employee-facing web app my team hosts. Turns out that in 15%
of connections with IPv6, the IPv4 is coming from a subsidiary VPN, but
the IPv6 isn't VPN'd -- supporting your point. (That number may be
artificially low, in that not all of our business units restrict the
users' source IP.)

When you get big enough (and go through enough mergers & acquisitions),
RFC1918 runout becomes a serious, legitimate concern. That's been a big
selling point for me.
