Projects (e.g. Xfce) usually tend to go (very) conservative wrt to dependency requirements, anticipating distro latency with adopting new releases. Some Linux distributions may literally take a couple of years to pick up a future Qt release. For instance Ubuntu Trusty LTS ships 5.2.1. Their latest release, Vivid (not LTS), is shipping 5.4.1. Their current beta Wily (still not LTS) is as of now shipping 5.4.2. Their subsequent LTS release *might* pick up Qt 5.6, but this will depend on Debian and on actual release dates.
So as far as Trusty users are concerned (likely a big chunk of the Ubuntu user base), if 2.2.0 depends on Qt 5.6 they will be locked into Qt 4.8 for the entire 2.2.x series. I don't know if the benefits of depending on Qt 5.6 outweigh such concerns. Maybe if we relied on ifdefs to support in parallel Qt 5.2 and 5.6, but I hear this can cause maintenance nightmares...
