IIRC, KDE 3.x made a lot of hard-coded assumptions about running on a desktop. Plasma was a re-write to be independent of the display and using Qt-Quick that Nokia had crafted for Symbian/Meego. But it's an egg and chicken problem. With no readily available KDE mobile hardware, developers won't port their desktop software to a 5 inch touch device. But in the past few weeks we've seen the Plasma team reach out to develop halium (common hardware base for sailfish and Ubuntu touch etc), assist with packaging for postmarketOS and this purism phone. So that's 3 backends make Plasma run on.
