I think these kind of things are more for applications. There, 
you determine what the regular patterns are, and you write 
tiny utility functions that wrap these in a single call.

But what those typical patterns are depends on the application, 
so I don't think this belongs in the library. At least not in 
the C library.

Language bindings for languages that work usually on a more 
abstract level could provide higher level functionality. For 
instance, for my Go binding, there is no setsockoption or 
getsockoption. There's a separate function for each option 
(which also works well with the godoc system), and there are 
even some more higher level functions.

But what type of higher level functionality is required also 
depends on the language. Czmq has things that make no sense in a 
Go binding, because Go does things in a different way.
