With the recent talk about “Elegance” I proposed to the KWin mailing list to no longer ship some of the KWin decorations as part of the default installation.
To make it clear: The proposal is not about forbidding people to use those decorations. The current idea is to move them to the “KDE Artwork” module where they are still available to all SC users if they choose to install that package.
I’ve posted a poll to find out which of our shipped decorations are even used.
You can find the poll in our awesome KDE Forums.
