Debian Jesse is going to have Gnome3 as the default desktop.
The desktop re-qualification page, used to help choose which desktop will be default, has in the Jesse version a weight for systemd integration, and of course only Gnome3 does it (at least for now). This will surely make the systemd/gnome3 fanbase happy, but possibly will make others unhappy, as it [may] be seen as another step towards mono-culture, until we soon end up with all distros being redhat clones.

Product tying.
Go ahead, try to run "GIMP the image editor" with the "wrong" init system. There is no rational reason to product ty those unrelated tasks unless you have a hidden agenda, and hidden agendas aren't usually very good aka they're hidden for a reason.
