It seems to me, that most people who aren't using CSSU (with few noteworthy exceptions) aren't just knowledgeable enough to know what it does (posts, claiming that CSSU main feature is portrait mode - LOL - or that cameraui2 can't be uninstaled), or are FUD believers (mystic "widget" incompatibility, WTF?).

Well, it's FOSS, so everyone is free to use whatever he/she want. Just don't cry, when something You would like to have require CSSU and developer isn't interested in releasing version compatible with non-CSSU devices. Or, Your bug report can't be confirmed, cause you use ancient QT or whatever. It's like requesting every developer to write for PR1.1.

CSSU is Maemo "upstream", no matter if someone like it or not. Of course, there is always "plausible deniability" available, so no one is forced to use anything
