Obviously Nokia will not push it to an official firmware, the question is if we can get it in a community SSU. The biggest problem is that on Maemo 4.x we don't have the option of sticking it in /opt so will use up precious root space (and we can't put it directly on SD storage as it has a noexec flag). The number of people working from cloned/SD boot setups is very small compared to the number of devices in total.

I had a patchset (and sort of even given the green light from some Nokians) to try and make a loop-device based storage for Qt. Now, that did work but I never felt it was stable enough to release it through Extras. But you raise an interesting point, I'll try and talk to stskeeps and see whether this can be resolved on an SSU level.
