Sure, modules can be split up in ways that are not useful and I haven't
doublechecked all of the dependencies between them to see if any can be
merged, but this not a large concern for me.

When I saw the word concern in the original comment, it implied a certain
amount of distress.

Where and how the modules are split up doesn't distress me right now
because it's an easily solvable problem and the only downside is
possibly having to remove more modules. I've always used a script in
those situations.

Regardless, there are bigger problems that worry me more than the split
of modules, atleast right now.
