Since this is about disk size, I proposed already quite long ago to not
ship the source *.py code, e.g. there could be something like:
python-foo-source
python2-foo
python3-foo
And in the python{2,3}-foo could be "Suggests: python-foo-source" (or
Recommends, since there were some voices that the python code is so much
needed on production system ....).
Would be nice if you can spend some cycles on this. The size benefit
would be much bigger IMO.

>
> Change owner(s):
> * Miro Hrončok <mhroncok AT redhat DOT com>
> * Petr Viktorin

> * Charalampos Stratakis
>
> Separate several subpackages form the python3 packages - a
> system-python(-libs) that can be required by various tools that
> consider themselves "system tools".
>
>
> == Detailed Description ==
> python3 package to be split in several more subpackages:
> * system-python-libs - a subset of standard Python library considered
> essential to run "system tools" requiring Python
> * system-python - /usr/bin/system-python binary (interpreter) for the
> tools to be able to run, provides system-python(abi)
> * python3-libs brings in the remaining subset of standard Python
> library and will require system-python-libs, thus packages requiring
> it (directly or indirectly) will get the entire standard Python
> library
> * python3 still requires python3-libs and provides python(abi)
>
> The term "system tool" in this context means any package where a
> maintainer wishes to require system-python package instead of python3
> package.
>
> Any package requiring "python(abi) = 3.x" (currently all Python
> modules and apps) will still bring in the entire standard library and
> thus will not be affected by this change in any way. Since this
> dependency is automatically generated, macros will be provided to
> remove it and depend on "system-python(abi) = 3.x" instead.
>
> If a package maintainer wishes to depend on system-python instead of
> python3 it is their responsibility to cooperate with the maintainers
> of all the Python dependencies of their package and do the same thing
> there. For example consider package foo requiring python3-bar; if
> foo's maintainer wishes to require system-python instead of python3,
> they must be sure to make sure python3-bar does this as well,
> otherwise the depednency chain would bring in python3 package anyway.
>
>
> == Scope ==
> Proposal owners:
> * determine what the essential subset of the standard library is
> (investigate packages that later might become "system tools")
> * split the subset into a subpackage system-python-libs
> * create system-python binary and package
> * invent macros to change the requirement of python-abi
> * test if present packages requiring python3 or python-abi = 3.x work
>
> Other developers: N/A (not a System Wide Change)
>
> Release engineering: N/A (not a System Wide Change)
>
> List of deliverables: N/A (not a System Wide Change)
>
> Policies and guidelines:
> * introduce a change to Python packaging guidelines for package
> maintainers to be able to profit from this change (after the
> implementation is ready)
>
>
> Trademark approval: N/A (not needed for this Change)
