Yeah, good point. The server is configured to content negotiate where
there is only one variant to pick from. Kind of like an automatic
permanent redirect but without the cache-ability. So presumably Apache
could spot the fact that there is only one variant and then not set

Except I'm pretty sure that HTTP will require that servers allow for the
number of variant to change at any time. So the server shouldn't adapt the
cacheability based on the fact that there is only one variant *at any
particular time*. So we are back to a manual CacheNegotiatedDocs for sites
that know they'll only ever have one variant. Ok.
