This has always been somewhat frowned upon, but it's not that uncommon.
Offhand, I can think of python3-configobj, which upstream is in the
process of tidying up.

Sometimes we do the one, sometimes the other. It depends.

A famous example is pkg_resources, which is shipped in setuptools,
upstream. We packaged it as a separate module, because it's a runtime
dependency of many packages, but they don't need the whole of setuptools
at runtime.

When we split packages like this, it breaks our automatic dependency
generation tools.  They understand upstream's dependency declarations,
so we have to manually add dependencies to packages that depend on split
libraries.
