Not really. If it sees "DAV:basicsearch" in the DASL header upon OPTIONs, it
knows that the resource at the request URI *is* a search arbiter. Absence of
the DASL header doesn't really tell anything, because the resource might not
be aware of possible search arbiters.

I don't agree. If every resource can act as search arbiter, this is trivial
to detect (using OPTIONS or PROPFIND
supported-method-set/supported-search-grammar-set). If not, there's really
not a lot we can do to help the client.
