I think you're missing a Netbook/Laptop profile in-between Desktop and Tablet.
Maybe even the two split up.
When I'm at home, I use my laptop as a desktop. Power is of no concern, and I
even build code on it.
But when I'm travelling, I notice that the KDE environment sucks at power
consumption. I would even go as far as to say that power consumption is an
issue in any segment and applications shouldn't wake up unnecessarily, nor
send broadcasts on D-Bus unnecessarily.
Of import is the Netbook form factor: it's like the desktop, but on a smaller
screen. So maybe it won't affect kdelibs, but the apps themselves that want to
address this segment.

Please read src/corelib/xml/qxmlstream.h:
// These platforms do not support symbol moving but allow it to be duplicated:
// Microsoft Windows (COFF PE executable format)
// special case: Windows CE wasn't supported before 4.4.0
You can't move the symbols further down the dependency chain on Windows. You
have to copy them.

Please address too the kded dependency issue along with the "klauncher-less
