SUMMARY

To me it looks weird that Kwin has lots of dependencies which have nothing to do with UI/X11/rendering.

STEPS TO REPRODUCE
# dnf install kwin-x11

RATIONALE:
Make KWin more suitable for environments outside of KDE, speed it up, make it cleaner.
Comment 1 Nicolas Fella 2021-04-20 17:03:11 UTC 
One of the settings modules provided by KWin uses a widget provided by KIO, which depends on quite a few things that are otherwise not used.

Avoiding that should be relatively easy to do, but it won't magically make things faster or have any noticeable effect other than disk usage
Comment 2 Nicolas Fella 2021-04-20 17:04:28 UTC 
In particular it's the KUrlRequester in https://invent.kde.org/plasma/kwin/-/blob/master/src/effects/cube/cube_config.ui#L67
Comment 3 David Edmundson 2021-04-20 21:27:08 UTC 
If anything is actually unused, you can make a very specific request.

This is unactionable as a bug report
