Filter A records in an IPv6 only environment

I recently came across an issue where the user program preferred IPv4 over
IPv6. This is a problem because I've created a network that is IPv6 only.
I'm currently using NAT64 to provide access to services that don't have any
Now this particular program could work if the DNS records didn't provide A
records. I would rather do everything I can as an admin to make the network
just work instead of waiting for all of the end user programs to be fixed,
so I started working on filter-a functionality to filter out A responses.
Currently implementation status is that it sort of works, which is further
than I expected to get in 2 days.
I wonder if anyone in the community is interested in me sharing the work,
and if I should go to the effort to publish the effort?
If anyone is curious, the offending program is nodejs and npm.
