No, of course not, for the reasons you cite. But as of now, the owners 
of the vocab *have* moved it to a new location (and promised to get 
*that* back online) and, as there's a doc in /TR space that refers to 
it, something needs to be updated on our side.

Something like this has been lurking as a future problem for a long time 
of course so part of my strategy here is to see how the community at 
large reacts to this real world case - and then see how W3C might be 
able to help, bearing in mind all the usual sustainability issues.
