What happened for the initiave to allow Tor access to TMO as a hidden service?

That could be done so that either the access would be read-only or accepted-login only and it would be very easy to set up as there'd be only the one channel to block (meaning, Tor-internal access as hidden service)

Additionally I guess it would cut just about all the random-access-malicious-users-using-Tor-just-to-try-it as not so many would even try to find out that we actually have a hidden gateway.
