See an example of this approach, based on an IRC chat excerpt from #pypa

(10:45:14 AM) [Tritium]: if you pip install toga with no dependencies,
nothing will be installed. The toga package is a meta-package - its
just a setup.py file
(10:45:40 AM) [Tritium]: its like a distro metapackage; existing only
to depend on other packages

The example can be found here:
