I have no idea why Fedora isn't upstreaming this (or I know why?). Anyways, attached to this bug is a patch that implements systemd support in libkworkspace. Do whatever you want with it. Reproducible: Always
Created attachment 347626 [details, diff] add systemd support to libkworkspace
Will be shipped with 4.11. Can be tested by using kde-live.
