Missing systemd user services

I just noticed a couple of systemd user services related to Plasma that show as not-found:

• plasma-baloo.services
• plasma-foreground-booster.service

They appear to be related to this MR, !366 (merged), but I can't find any evidence of the unit files referenced in the commit, which are the same ones showing as not-found. Are Kubuntu's packages failing to include these files, or is something else at work?
