Okay, let me try to make this more clear.

First some example dependencies for the switch from monolithic to
split qt which happened between qt-4.3 and qt-4.4:

monolithic phase:
DEPEND="x11-libs/qt:4"

transition phase (monolithic and split qt coexist):
DEPEND="|| ( ( x11-libs/qt-gui x11-libs/qt-opengl ) =x11-libs/qt-4.3* )"

split phase (only split qt left):
DEPEND="x11-libs/qt-gui x11-libs/qt-opengl"

In the monolithic phase there was no meta ebuild and everything
depended on the monolithic qt ebuild. During the transition phase the
dependencies have been separated to make it possible to use either the
monolithic qt-4.3 or the split qt-4.4 without any ebuild depending
direct on the new qt-4.4 meta ebuild but just the split parts which
are needed by the application. After the removal of the monolithic
qt-4.3 ebuild which already happened the ebuilds need to depend on the
split parts only. So there should be no ebuild in the monolithic phase
and almost all ebuilds in the transition phase that will be slowly
converted to the split phase.

So as far as I see the new qt meta ebuild wasn't needed at any time.
