Comment (by teor):

 Also, can we do the whole HS protocol at once:
 * intro point v2 and v3: close the HS INTRODUCE side if both sides are
 directly connected (#22689)
 * HS v2: refuse descriptor uploads if the service is directly connected
 (#22688)
   * we can't refuse direct descriptor downloads, because Tor2web uses them
 * HSv3: refuse descriptor uploads and downloads if the client or service
 are directly connected (#22688)

 I'll see if I can do these in 15 minutes,
