Unix domain sockets allow connecting via another program. Why not just have that other program listen on a localhost port? That's then exposed to all processes on the host.

Looks good!
Would you please also add a call to providers.RegisterCredsMetadata()?
This is a new feature, which is covered in Step 4 of https://docs.dnscontrol.org/developer-info/writing-providers
You can see an example in #4297
Thanks!
P.S. If you wish to do that in a separate PR, please let me know and I'll approve this as-is.

My usecase is doing AXFR/DDNS via DNS-over-TLS with PKCS11, and to a server that has a self-signed cert whose pubkey pin I want to verify. This could plausibly be natively added to dnscontrol, but it would be a fiddly amount of config in the AXFRDDNS provider.
Unix domain sockets allow connecting via another program, that already exposes lots of the above configuration (stunnel/ghostunnel).
Why not just have that other program listen on a localhost port? That's then exposed to all processes on the host. Unix domain sockets are restricted by file ACLs.
