--- Comment #2 from Piotr Popieluch piotr1212@gmail.com --- DNF is not available in RHEL6 and 7 which are still supported up to 2028. This is a really useful plugin which I would definitely use as sysadmin. I do think it is worth the work.
Did you already found someone which is willing to sponsor you? Do you want to become a package maintainer or are you just interested in getting this single package in Fedora/EPEL? If you are just interested in this package it would probably be faster if I would take it over from you and make you co-maintainer.
