Who is advocating "going nuts"?

You're criticising a wide concept by considering one suggested example.
Nonetheless, there are sufficient "dates of death" on the web to suggest
that marking them up, semantically, would be useful, and incorporating
them in hCards, ditto.
This is especially relevant when incorporating hCards into other uFs,
such as those for citations and reviews
