Yes, reverse PTR record back to primary name would be nice. Domain 
suffix should not be necessary. /etc/hosts allows aliases, so you can 
have line like "  primary.example.com primary". That would make 
primary.example.com a primary fully qualified domain name. And 
"primary." just an alias without matching PTR record. Either just 
address or even CNAME to primary.example.com.

It seems to me it could be a special implementation of Cache DB module. 
I admit I have never tried to use CacheDB module yet.
