Hello,

=E2=80=9Cpython2-=E2=80=9D packages are mostly a convenience for users who=
=E2=80=99d like to use
them directly.  For applications, =E2=80=98package-with-python2=E2=80=99 ta=
kes care of
=E2=80=9Cconverting=E2=80=9D complete DAGs to Python 2, so those =E2=80=9Cp=
ython2-=E2=80=9D packages
don=E2=80=99t matter much.

It seems too early to get rid of everything Python=C2=A02, as Konrad
suggested.

Softening the policy to add =E2=80=9Cpython2-=E2=80=9D packages sounds like=
 a good way
to move forward.  For new packages, it=E2=80=99s quite simply: just don=E2=
=80=99t
provide the =E2=80=9Cpython2-=E2=80=9D variant unless it=E2=80=99s required=
.  For existing
packages, it seems trickier though.  Which packages would we remove and
when?

Thanks,
Ludo=E2=80=99.
