Missing dependencies in python2.7 image

[drigz]

The python2.7 image installs the following packages:

        packages["zlib1g"],
        packages["python2.7-minimal"],
        packages["libpython2.7-minimal"],
        packages["libpython2.7-stdlib"],

However, libpython2.7-stdlib depends on more: (note - this is from the debian:jessie-backports image, which already has some packages that distroless doesn't - eg libreadline6).

The following extra packages will be installed:
  libexpat1 libffi6 libpython2.7-minimal libsqlite3-0 libssl1.0.0 mime-support
Recommended packages:
  file

Are these dependencies intentionally excluded? Should/could the deb extractor check dependencies or is this out-of-scope?

I ran into this while trying to use defusedxml inside a container: tiran/defusedxml#10
