When I place the wrong finger on my touchID and press the home button once, it shows me the pin entry to get into the phone. No multiple presses, nothing. First bad read, shows the pin entry.

As for the touch ID - try double clicking the home button with a finger that has no touch ID, it does not show a PIN entering screen. I used to double tap all the time before to quicker unlock the phone and swipe to enter a pin, now its' quite annoying and not as fast.
