The API docs for the various vir$OBJECTGetConnect functions
contain a warning
WARNING: When writing libvirt bindings in other languages, do
not use this function. Instead, store the connection and
the domain object together.
There is no reason why language bindings should not use this
method, and indeed the Perl, Python, and Go bindings all use
these methods.
This warning was originally added back in
commit 3edb4bc9fb

* src/libvirt.c python/generator.py: some cleanup and warnings
from Richard W.M. Jones
IIUC, the rational was that these APIs do not need to be
directly exposed to the non-C language, as the language
can expose the same concept itself by storing the original
virConnectPtr object alongside the virDomainPtr. There's
no reason to mandate such an approach though - it is valid
for languages to expose this directly if that suits their
needs better.

There are also a couple that were very uninformatively just logging
the value of the pointer rather than the string itself:
* the "name" arg to virNodeDeviceLookupByName()
* wwnn and wwpn args to virNodeDeviceLookupSCSIHostByWWN()
All char*'s that make sense should now have their contents logged
rather than the pointer, and all %s args should now be inside
NULLSTR().
