Something to consider doing for the 1.6-and-earlier versions of the book?

In my response, I thought it would be valuable even for the youngest version of the book so that forks thereof that spring up around the Web would point to the canonical location. I may have been too hasty, though, as I *think* I just read that this tag only works (as in, is recognized and handled as expected) when the source and canonical target are on the same server.
