Some people seem to be forgetting what this is being used for. This is an OPTIONAL replacement for the pass code. However you feel about its level of security it is definitely more secure than a passcode which is the other option. If someone wanted to target you for whatever reason then how long would they have to follow you with a high zoom camera before they would see you type the passcode in? The passcode/touch ID is to stop opportunistic unlocks not a determined attacker.
