Apps that have passed the testing process (i.e. those in the maemo.org repository) do not install to the rootfs. If you've installed apps from extras-devel or extras-testing, you've implicitly accepted that there may be issues with these (including, but not limited to, taking up rootfs space). Themes are a bit more of an issue - the PR1.1 update has (from what I've read) introduced a way to have themes residing on /opt, but earlier themes will not be doing this. The main issue currently is with shared libraries (especially Qt4.5) which install to the rootfs - this has been fixed with Qt4.6 so there's obviously work in progress on this.
So when you install in root, not optified apps...the files in rootfs will not be removed when you uninstall?
no clean up command available...seems that re -flash is the only option.

No, any (non-devel/testing) apps uninstalled will clean up after themselves, removing any files they installed and (if done through App manager) any dependencies which are no longer required.
