Tangerine-icon-theme has been dropped from the seeds in favor of simply using ubuntu-artwork package which pulls in the new slick humanity theme.
There are 47 scalable icons which are provided by tangerine and are not in the human theme. So I think it is reasonable for human theme to depend on tangerine for those who would still want to use that theme after karmic.
