Just simplicity for the moment; I’m not entirely happy with the state of opam 
package explosion at the moment and the pressure it’s putting on the opam 
solver.

I’m not overly concerned with build-time dependencies for ppx — the danger is 
when they get unconditionally linked to the runtime.  There are various 
initiatives that have been ongoing to get ppx libraries working with trunk 
OCaml more reliably, so that aspect of building them will only get easier with 
time.

Anil
