We could make working versions declare a new HSIntro version, and then make clients require that version. When we fix high-impact bugs in future, we should consider adding a new protocol version, and making clients require it. That's what protocol versions are for, -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/27841#comment:35> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
