For those who say "just tap the power button," you are missing the true point of the Decline button. It gives you the option to send a quick reply text to the caller, like "I'm in a meeting" or "I'll call you right back." This is a truly beneficial feature when you need to let the caller know that you are ignoring their call for a reason.
The reason why it could be missing when the phone is locked, is because it allows you to send a text message to someone when the phone is locked and you may have it turned off. However, you can "supposedly" allow this feature under Settings>General>Passcode Lock>Reply with Message. However, I too have found that this is not working even when enabled. That's the true question and the true problem.
Have you let Apple know how you feel?
