Yeah, know that you can set it for each client (Linux/Windows/macOS). My
problem is many mobile clients (iOS) where setting this up is impossible. And
Netflix / Amazon / whatever becomes an issue... so network-wide solution would
be cool!
What sort of issue? Do you have a broken IPv6 network?

My goal is to successfully resolve AAAA only for hosts that are IPv6 only and

I can't answer your question about doing this inside PDNS, but just wanted to
mention that you can configure individual hosts to prefer IPv4 over IPv6 when
both are available.
In Linux this is done by configuring /etc/gai.conf, e.g. for Ubuntu just
uncomment this line:
precedence ::ffff:0:0/96 100
I don't really do Windows, but I understand the corresponding feature is called
"prefix policies":
