Comment (by teor):

 Replying to [comment:28 zyan]:
 > Will fix. On further thought, maybe just get rid of the pref entirely
 until #17228? I can't think of an immediate use case where one would want
 to enable cross-origin onion referrers.

 Onion-sites using sub-onions to host (static) content.
 Or the onion-per-role design that Facebook (and perhaps other sites) use
 (I think it's upload, static, and dynamic).

 Perhaps we could send an email to tor-dev before we decide whether we need
 a preference?
