That's the problem - the submodules are not automated. They are
half-automated, and the rules for when the automation works and for when
the automation falls apart are not intellibible for the general Joe
Developer.

You might spend a few days studying how they behave exactly, and then you
will know. But unless you will use them every day you will forget again,
because the rules do not lend themselves to some abstraction easily
understood by humans.

Thanks
