One possible value we could use is

about:blank

There is an I-D kicking around somewhere that defines the about
scheme.  The author might be amenable to allowing about:blank to be
used here (e.g., as a "placeholder" URI when no other URI is
appropriate).

Another possibility is to use something like

about:noreferrer

and define about:noreferrer to return a resource that describes what
the value means in the Referer header (e.g., the relevant requirements
from HTTPbis).
