why, oh why (do gtk2 pkgs depend on gtk3 pkgs)?

Trying to eliminate gtk3 packages from my F14 alpha rc 3.1 LXDE spin, I see:

gnome-bluetooth-libs-2.90.0-4.fc14.i686 has missing requires of 
libgdk-x11-3.0.so.0
gnome-bluetooth-libs-2.90.0-4.fc14.i686 has missing requires of 
libgtk-x11-3.0.so.0
gnome-themes-2.31.6-1.fc14.noarch has missing requires of gtk3-engines
libcanberra-gtk2-0.25-2.fc14.i686 has missing requires of libcanberra-gtk3

Why do gtk2 packages require gtk3 packages?
