can muon 2.1 be a solution?
possible, given sufficient testing. No one's worked on packaging it yet.
I prepared a Muon package, available on copr (https://copr.fedoraproject.org/coprs/scorpionit/Muon/). It seems to work, but there are still some issues. Anyway, soon or later I am going to build the Git version.
Thanks! muon looks pretty nice, I'll clean it up a bit and submit for pkg review asap.
review submitted, bug #1202591
Marking this one wontfix, we've got plasma-pk-updater and muon as alternatives now.
