I would appreciate if you could build python-django-debug-toolbar for EPEL8. I've checked that master branch builds fine there and according to my testing works. Feel free to add me as co-maintainer. This package and its dependencies are built in https://copr.fedorainfracloud.org/coprs/ignatenkobrain/netbox/packages/.
Thank you for stepping up, I've added you as co-maintainer here. Personally, I don't have any interest in epel8 builds.
