As hinted, threatened, promised, etc... :)
kf5-5.33.0 and plasma-5.9.4 are built and on the way to updates-testing for
fedora 25,

respectively.
I've put both batches of updates into kde-testing repo for quicker feedback
too.
Note: plasma-5.9.4 was built against kf5-5.33.0, so you almost certainly
need both (not *just* plasma-5.9.4) for proper testing.
Enjoy and let us know what breaks.
