Which would make it even more heavyweight by forcing now the client
to use campl4, to download your deriving library, to understand
this deriving stuff, to infer the names of the functions
now that they will be hidden/internally-generated by campl4 ... 

Look at the ocaml standard library, why do you like it ? 
Because it's simple. A few types, a "kernel" of essential functions,
not too much functors (well in fact I would prefer even less functors
such as a simpler Map and Set like the Hashtbl module). KISS.
