why not get this finally entirely out of the way: suggested/recommended dependencies support, like SDEPEND, http://bugs.gentoo.org/327701 as in, threat them as RDEPEND if user has the option to pull them in enabled, otherwise print an uniformed postinst message as a bonus, this solution would also allow USE dependencies to work and would replace some cases of 'has_version foo/bar[use]' - Samuli
