The goal of the specification is to provide a set of rules that conformant user agents must obey out of the box, without any extensions. Features that are supposed to be ignored do not make good candidates for including in the specification, except as extensions to HTML that are explicitly supported.
The HTML 5 spec already includes the many features which browsers currently (mostly) ignore - the <meta> tag, the "type" attribute on most links and so on. The fact that HTML includes a <dfn> element doesn't mean that every browser has to have a built in dictionary for storing all the definitions people collect on the web, but the element is there for those people who want to use it. Browsers *could* do something useful with <dfn> if they liked, but none so far seem to have done so.
