AFAIK, universe and multiverse are not officially supported in Ubuntu -- in other words, they don't get security fixes from the Ubuntu security team. Ubuntu gets most of their universe and multiverse packages from Debian unstable, some from Fedora, and some from the unofficial repositories available via apt-get.org. These packages are potential security risks and they are not guaranteed to work at all.
Pre-release packages can only be recommended for advanced users who can fix things when they get broken. Last time I looked, Ubuntu's backports repo was almost empty. Pinning is too difficult for normal users. Normal Ubuntu users should make sure that universe and multiverse are NOT enabled and they should stick to official Ubuntu releases. They should also install security updates as soon as they become available, although any updates have the potential risk of breaking your system. Unofficial package installers, like Automatix, should be avoided.
