Not so in in the real world. In the real Internet, people connect to
services by means of domain names. It is entirely possible for someone
(like Akamai) to offer some sort of proxy services for websites etc.
that cannot implement IPv6 easily. The website owner would insert AAAA
records in their DNS zone pointing towards the proxy operator's
addresses. The proxy operator would then manage the data transfer
between the IPv4 and IPv6 network, or if the content is static, they'll
just serve it from a copy. A lot like Akamai currently does now.

Precisely!

There are stupid technical tricks that can be used to make v6-to-v4
connectivity work. You will never find these tricks documented in an RFC
but you will find people who build a business around selling magic boxes
and proxy/gateway services as described above. It has happened before
with route optimization and with WAN optimization and app-in-a-box, etc.
It will happen again with IPv6.
