It's required by KApplication and while that's in kde4support, it's still there (as well as KDE4 clients)
So "yes, we need that everywhere" - for now.
Clients seem to default the env to false, so uncoditionally setting it true is wrong for sure.
It'd rather be "multihead = (screenCount > 1);" (ignoring the ini) what however would be a feature loss.
=> Proposal
users should be able to pre-control the variable in eg. ~/.kde/env (or wherever the Plasma 2 equivalent is)
If the variable is set to false, it remains like that.
If not (ie. it's not set or set true resp. anything but 0/false) it becomes true if the screen count > 1
Spares the ini lookup, but I don't think you get around
xcb_connection_t *c;
int screen_count = xcb_setup_roots_length(xcb_get_setup(c));
without risking to really break stuff (the suggested approach still causes a transitional break)
