---------------------------------+------------------------------------------
 If the !TunnelDirConns torrc option is off,
 `hid_serv_get_responsible_directories` skips over any HSDir relay that
 does not advertise a !DirPort when building its list of hidden service
 directory nodes 'responsible' for a descriptor ID.  This behaviour cannot
 possibly be correct.

 The !TunnelDirConns option should not affect a Tor instance's use of
 hidden service directories, as clients and hidden services ''always''
 connect to hidden service directories anonymously (thus using
 `BEGIN_DIR`).  Also, in order for the hidden service directory system to
 work correctly, every Tor instance must consider the same set of hidden
 service directories to be responsible for a descriptor ID, regardless of
 its configuration settings.
