An author need not be the first author.  An editor charged with maintaining
a site where Julian date markup is used would have to learn Julian date
markup.  In this way, whenever we include a feature that we consider
optional, we ultimately make the editors, if not the primary authors, learn
about it.
Nobody wants to fail at 20% but not everybody can afford not to :-(
