You have an interesting case here.  Like spot, I lean towards the *.cma
files being available from the main (non-devel) package as the toplevel
and interpreted OCaml scripts won't run without them.  They are loadable
modules in this sense.

The fact that they are also included statically in compiled OCaml
programs seems to be a red herring for this decision but I'm sure their
dual nature will raise other interesting issues later.
