Right, for some reason I thought PGobject was abstract.  It's still not
great to force them to include postgresql specific code in their app, but
I don't see a way around it without abandoning the goal of removing the
use oid zero.

In this case yes, but not in general.  The driver types it as text so this
really comes out as ?::text::cidr which is different from unknown -> cidr.
In this case an explicit cast is available, but this won't be true (by
default) of other types.  Consider:

jurka=# select '(1,2),(3,4)'::text::box;
ERROR:  cannot cast type text to box
