That seems quite brittle and unprecise and are things that get in the way/you have to consider when you need to debug build systems.

It seems to me that OCaml's build rules are already sufficiently complex so that the tool that is supposed to help us to manage them doesn't introduce more noise in the system.

More specifically I think that most build system developers out there would agree that having a clear ocamlfind sub-command that allows us to query the *exact* flags a package is supposed to provide us along the well defined phases: pre-processing, compilation and linking in the native and bytecode dimensions would be of great help in general.  

Would you maybe consider implementing something along these lines ?  

Best,
