I think that a cleaned up root directory is by itself already adding a
lot of value because it makes the entry points into the Git codebase
more explicit. As I said elsewhere, the value is not in making the code
that is part of "lib/" itself more discoverable. The value is in making
everything else more discoverable.

Ultimately though it's a subjective change, so it's hard to argue about
that as I cannot present any hard facts.

Thanks!
