--- Comment #35 from Kevin Kofler kevin@tigcc.ticalc.org --- I can readd the Provides: deprecated(), but obviously with the exception that plasma-workspace-x11, which is technically a "new package entering Fedora", is allowed to require kwin-x11, as it did when those were both still subpackages.
I agree that other packages should probably not require kwin-x11. At least as long as it uses the shared libkwin. But if KDE upstream goes ahead with their plans to fork libkwin into 2 separate versions for Wayland and for X11, then people may want to build window decorations against both kwin-wayland and kwin-x11, obviously in separate subpackages with separate Requires.
Why I wanted to remove the Provides: deprecated() is because its purpose is normally to be put on a package that is planned to be dropped from the distribution some time soon (to avoid new dependencies creeping in, slowing down the phaseout). But I am not planning to drop kwin-x11 any time soon.
But if someone wants to submit an application that Requires: kwin-x11 for no good reason, I agree that that would be a very bad idea. (The application should not Require any specific window manager, let alone a specific build of KWin.) So if that is your worry, we can leave the Provides: deprecated() in, as I said with an exception for plasma-workspace-x11.
