* Optimize the dependency tree in $this->modules.
*
* The optimization basically works like this:
- * Given we have module A with the dependencies B and C
- * and module B with the dependency C.
- * Now we don't have to tell the client to explicitly fetch module
- * C as that's already included in module B.

* This way we can reasonably reduce the amount of module registration
