 Similar to #21284, some single onion service users want to be able to use
 hidden (double onion) services most of the time, and single onion services
 occasionally with trusted peers.

 For example, see the OnionShare use case in:
 https://lists.torproject.org/pipermail/tor-dev/2017-January/011782.html

 One potential anonymity issue is that any introduction and rendezvous
 points see the single onion service's IP addresses, as does anyone with
 access to the networks those relays are on.

 But anyone with access to the network the single onion service is on also
 sees its IP address, and that it is creating tor traffic. So I'm not sure
 how much of a threat this is.
