No, I'm saying that people are installing packaged versions of recent
releases of python libraries. But they're skeptical about upgrading
their libvirt packages. With the work done to enable libvirt be uploaded
to PyPI, can't the two be decoupled? Can't we have packaged versions of
the recent python bindings on PyPI that are independent of the base
packages containing libvirt.so and libvirtd?
(Or I could be completely misunderstanding the issue people are seeing)
