Nokia managed to upgrade Qt to 4.7 in their Maemo distribution and it got pushed to all devices without causing any problems so far. Their standards for avoiding churn are pretty high and their update scheme is extremely conservative for stable releases. Nevertheless they updated Qt. But they have a pretty good reason for doing that (aligning with future versions of MeeGo and Symbian). So what does a F13 user gain from an upgrade? Is it worth the risks?
QT isn't the default toolkit in Maemo and it was only introduced at all in the PR1.2 release which only came out around 3-4 months ago so its not a core part of their UI experience on maemo.
So that's not really a good argument for upgrading it in F-13.
Also, I'd assume that Maemo explictily ships/supports a much smaller set of software than Fedora, so they can explicitly list all their dependencies that may need fixed.
