The 4.7 and 5.5 do satisfy everyone. You people that can't seem to stand an extra centimeter in height and a few millimeters in width make up about 0.00000000000001% of the market. Apple isn't concerned about that.

You really think you could press hard enough to deflect a piece of sapphire in any measurable amount? Not even close.
You're wrong. Plenty of people want a 4 inch phone. There are plenty of people on here who want a usable one handed phone. The 6 is usless to people.

Yes. If that is really a big selling point for some users.
Once you go bigger and learn to live with the bigger screen real estate most people will not go back.
Plenty of people don't want oversized phones. IF Apple a ally gave people choice, having a 4,4.7 and a 5.5 iPhone 6, people would buy the 4 inch phone.
looks like I'll be getting a second hand 5S then when that goes switching to a different brand as for me being able to use my phone one handed is paramount for both usability, and not dropping the phone. I don't need sometbing that is too small to be an iPad and too big to be a usable phone.
