It appears the evdev flag for =dev-qtgui/qtgui-5.4.2-r1 is not being read from the USE_EXPAND INPUT_DEVICES and requires that it be added to the use flags for that package. Is there a reason why it can't read the USE_EXPAND flag? !!!

Does anyone have any thoughts about this? It should be trivial to implement, but I don't know enough about the meaning of the USE flag on this package to know if it makes sense.
I would prefer this too, so that evdev is switched on/off in one location. At least two other packages already have USE=evdev as well: games-emulation/dolphin-9999 kde-plasma/plasma-desktop
USE=evdev in qtgui:5 refers to the generic input event interface of the linux kernel [1]. It has nothing to do with input device drivers [2], or x11-drivers/xf86-input-evdev in particular. Therefore I don't think renaming the USE flag is appropriate in this case.

Current examples (consolekit has a better description): dev-qt/qtgui:evdev - Enable support for input devices via evdev games-emulation/dolphin:evdev - Enable evdev input support sys-auth/consolekit:evdev - For handling VT switching with a session controller.
