I would actually like this, and make it easy for us to build for
multiple Pythons (even if we don't do it by default in Fedora). This
is how openSUSE works with their "singlespec" model[1], and I have
come to appreciate it, even though I don't like some of the details of
the openSUSE implementation (such as weird parsing and rewriting of
stanzas for dependencies instead of the use of a generator and the
usage of alternatives, as shown in this example[2]).
