The friendzone occurs SOLELY due to a lack of attraction after the comfort/rapport stage. That's it.
Being 'not attracted' leads directly to the friendzone. They are not mutually exclusive occurances. Whether it's because the guy didn't escalate enough, or whether it's because the two of them simply don't fancy each other doesn't matter. It never implies you are a chance of hooking up.
It really does.
The 'friendzone' is the place guys go to rue 'missed chances'.
The 'friendzone' implies that the guy was keen - and probably thought he had a shot.
Otherwise it's just known as 'being friends'.
