So the fix if they do FTBFS would be to add ${python:Depends} or

There's another weird corner case I guess, which is, that related binary
packages that may contain some data but not necessarily the actual /usr/lib
code could start with python-.

For example, python-foo-doc or python-foo-common.  Case in point: for the
wheel package, I wanted the /usr/bin scripts to be shebanged python3.  The
multi-version build process leaves us with /usr/bin scripts in both the
python2 and python3 packages.  I throw away the python2 versions and move the
python3 versions to the python-wheel-common binary package.  That package also
contains the manpages of course.  It didn't feel right to call that
python3-wheel-common but I did want it separate from either the python- or
python3- library binary packages.
