The https://github.com/jazzband/django-model-utils package already has @carljm as a maintainer but given there was no release for more than a year and my current employer actively uses this package I'd volunteer to become a lead as well.

I recently attempted to release 3.2.0 jazzband/django-model-utils@d3d0881 but while the package was uploaded to https://jazzband.co/projects/django-model-utils/upload it is still pending approval to be release to Pypi.
