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]'
