You claimed this for the second time and i'm denying it for the second time.

The goal of fuzzing the version inforation is _not_ to 'hide bugs from user-space by
cheating on version'. The goal is to introduce uncertainty to attackers, so that a
honeypot silent alarm can warn the admin.

Why are you putting words in my mouth?
