It's pretty much the same as for urn:ietf:std:66, or even
http://example.org/ — is the latter of any use if there's no
HTTP client on the host in question?

Indeed, the majority of the World Wide Web software currently in
use supports only a tiny fraction of the URI schemes currently
registered. My guess is that this particular case is in the
GNUnet project TODO list, though.

Not quite. While GNUnet may use such an identifier as a key for
its DHT, it's possible to compute it for a given file
independently of GNUnet (for the purposes of validation, or
otherwise.)
While rhash(1) doesn't seem to support GNUnet CHK's (TODO?), it
computes BitTorrent infohashes just fine. Consider, e. g.:
$ rhash --simple --btih -- hello
aa95e34e2f7eac67d73ff479c135d5a75d2c8412 hello
$
Thus, it's already possible to use BitTorrent infohashes
independently of any BitTorrent agent software whatsoever. The
same should apply to the content-derived identifiers employed by
the other “file-sharing” P2P networks just as well.
