If I were to take your approach, and make generalized statements based on my own experiences, I would say many if not most actually do experience significant withdrawal symptoms for an extended period of time.
You need to take into account: dosage, age, health, life circumstances, and I would think even more before you can suggest even the slightest correlation or "average" experience.
I get what you're saying and I'm very glad it was easier for you than others, clearly. I think though, it's dangerous to others to make claims based on one person's experience.
