We've already determined that OCaml is ... special.

Here's the rule of thumb I've always used:

In the traditional library/binary model:

The main package is for libraries and components that another binary
would need to execute. I can't _run_ foo without libbar.so.6 being

The -devel package is for headers and components that are needed to
build that binary. I can't _build_ foo without bar.h being present.

So, in the OCaml universe, I'd say those .cma files fall into the main
package, as I can't run _foo_ without those .cma files present.

Note that I know absolutely NOTHING about OCaml besides what you've told
