Specifying English, or any other language, as a default value doesn't
seem right to me.

Realistically, the majority of clients will not do anything with this
information.  Those which *do* use it in some way will know best what
the most sensible behaviour is in the absence of explicit information.
So I propose that client behaviour in the absence of a specified
language is up to the client.

The search engine case seems the trickiest to me (compared to, say,
screen reading).  Statistical language recognition is a thing, but doing
it on every document in Geminispace is likely to be burdensome...
