Seems like a useful check to me.
kcheckrunning is a 5 line program.

Should I bring kcheckrunning back into kdebase/workspace?

here's the code:
#include <X11/Xlib.h>
int main()
    {
    Display* dpy = XOpenDisplay( NULL );
    if( dpy == NULL )
        return 1;
    Atom atom = XInternAtom( dpy, "_KDE_RUNNING", False );
    return XGetSelectionOwner( dpy, atom ) != None ? 0 : 1;
    }
