Sure - but if you are going to implement (say) mailto support in your browser, ought you not to at least make a token(!) effort to find out whether the user is who they're claiming to be ?
Plus, the scenario I outlined hardly adds virtually no new code to the browser. Is this more or less worthwhile than <blink> ... </blink> ? :-)
