Comment(by Sebastian):

 {{{
 < frosty_un> oh puppets we are wrong, it's not about blocking tor
 protocol, it's about downgrade from v2 to v1 by enemy. not sure what is
 worsiest thing.
 < frosty_un> we are talkking about expoiting #4592.
 < frosty_un> HMAcs easy bypassing with tcp window, nice isn't?
 < frosty_un>  viva la "This check is redundant". no rollback attack, only
 blocking tor protocol: server thinks it's a v2 while client using conn
 like v1.
