As much as I would like to see the transition happen,
Realistically, IPv4 will continue to 'work', for a large number of users,
for a very long time.
If you multiply your times by 10 (or more) and work hard, you might be
successful in phasing out most of IPv4 in DNS.
But forcing users to change seems like a bad idea.

I note issues like:
- Cloud providers (Amazon, Google, Azure?) only provide a private IPv4
address to virtual machines.  They use NAT to get an IPv6 address for
incoming traffic.  I don't know of any way to do IPv6 outgoing.  (I could
be wrong, still learning here.)
- Android does not support DHCPv6.
- DNS64 breaks DNSSEC.
- There are probably a large number of legacy hardware devices and software
programs that do not support IPv6, but will still be running 10 or 20 years
from now.
I expect there are many more, but those come to mind.
