Updates on this.. I plan to ask for Bluedevil and libbluedevil, libkscreen and kscreen, libmm-qt and ksshaskpass to be moved. I see some comments that the libraries may be used outside of Plasma but there's no problem with that happening, they don't quality for frameworks and they already get released with Plasma so it's just an update in projects.kde.org
user-manager looks like it could do with KConfig::KEMailSettings ported and then Account Details done away with, I'll keep it in kdereview for now. kcm-touchpad needs the feature of the shortcut for ktouchpadenabler taken and ktouchpadenabler disabled, I'll keep it in kdereview for now. polkit-kde is already in and has now been merged so master is KF5.
