ok. Do you know by any chance why BIND in particular is using this header?

right, this might makes sense for formats. But I would argue with 
another usecase, namely Custom Authentication
instead of HTTP authentication (BASIC or DIGEST).

Let's assume a resource is protected and a server would like to offer 
custom authentication, e.g. it would send
a HTML to a regular browser and some WebDAV specific XML to a WebDAV 
enabled client, whereas I haven't digged into
WebDAV far enough how something like this could be handled by the WebDAV 
spec.

All the best
