I think that Vicente is right in this case. Moving serialization support to
a submodule of DateTime will make the dependency report nicer _and_ it will
actually be correct from the perspective of an automatic downloader. If you
use DateTime, you'll get the DateTime repo, along with the serialization
support, but you will not get the Serialization repo (and its dependencies)
if you don't use Serialization. And this is exactly as it should be, unless
I'm missing something subtle.

It seems to me that this is a legitimate use of sub-sub-modules.
