[Dnsmasq-discuss] Bug report: authoritative zone transfers for PTR domains

Hello from a list new-comer.
Consider running on the network 10.0.0.0/8, serving DHCP on that subnet, and wishing to publish both the forward and reverse zones to secondary caching servers: example.com <http://example.com/> and 0.0.0.10-in-addr.arpa.
While dnsmasq creates and serves individually the necessary PTR records given an auth-zone option:
it does not believe it's authoritative for the PTR zone.
The workaround is to add:
The logic in the startup code is simple: the authoritative zones are exactly the set encountered in the options file; nothing else is implied. What results is inconsistency, because dnsmasq essentially lies by supplying an authoritative claim via NS and SOA records on 0.0.10.in <http://0.0.10.in/>-addr.arpa then refuses to do a zone transfer.
There seems to be little interest in reverse DNS zone transfers; this workaround is not found in the manage or anywhere I could find.
