If someone tracks Qt branch he probably doesn't want to rebuild KDE just
because he updates Qt. Thats one of the reasons for having BC in the
first place. If most people would always run the exact same version of a
library they built and app against then all we'd do is recompiling all
day long.

AFAIK: No. Distro's build kde when kde is being updated, but not if Qt
is updated. So Distro's build KDE 4.4.0 against Qt 4.6.x (x>0 probably)
but at some later point they'll be rebuilding Qt only and ship that to
the users.

I personally often update kdelibs, but much more seldomly update the
other modules from trunk. So I often compile kdebase against kdelibs
4.x.y and later run it against 4.a.b (a>=x,b>=y).
