Right. I'll ensure in future that I provide a summary, but I expect I can't be
expected to update it if it has a duplicate in another, more versatile tracker.

To summarise, plasma-discover currently expects that the aforementioned package
be included with any installation of itself due to the fact that there isn't
any presence verification code to determine whether the relevant context menu
entry is displayed.

Until or unless this is remediated by KDE
(https://discuss.kde.org/t/opening-update-kcm-from-discover-shows-blank-page-in-plasma-systemsettings/3149/6?u=rokejulianlockhart)
this package should be included.
