As I suggested, it seems that packages that use ttf-liberation do depend on it, so I see no reason to explicitly list it.
1) That's still not true for openoffice.org as of version 1:3.2.1-10, which only recommends the ttf-liberation package.
2) I don't quite get your argumentation. The ttf-liberation package contains fonts that substitute the notorious Arial, Times, etc. fonts found in other common *desktop environments*. I do not expect any other package to *depend* on them, but I expect them to be installed on a standard install desktop system and be available for usage in other packages (e.g. office software).
Please add this package to the desktop task. It is independent of the used desktop (Gnome, KDE, ...) and also independent of the office suite of choice (openoffice.org, abiword, ...).
IMHO, it should simply be there. - Fabian
