The more often you have to go scrounging for information elsewhere, the less useful a reference is, and the less likely a given feature will be used, thereby lowering the effective capability/utility of a language. Of course there are cost-benefit and declining ROI and TTM opportunity cost factors to consider, but unless more than (say) about 10 micro-acres of text is involved, I think it's probably worthwhile doing.
