The haptic feature also packed in last year iPhone 6S, even though, it doesn’t work for home button. And, recently launched iPhone 7 and iPhone 7 Plus coming with Taptic Engine (Physically Contact with Home button) for better haptic feedback than ever before. it gives real Sense of touch either you clicking single or double time, or you pull down the Notification Center etc. It needs enough presser so that you will not press it by accidentally. In Addition, Apple has also open the door for developers, since the company provides new API for them (developers) to add custom vibratory feedback to their applications. In short term, in rich iPhone included taptic engine is a form of MacBook track pad. If you dislike this vibratory feeling, then you have an option to control it means enable/ disable haptic feedback on iPhone 7 or iPhone 7 Plus.
I recommend that you should Turn on haptic feedback for getting something new user interface feeling. Because haptic feedback is only a single setting for System Controls and interactions. By the way, you can turn off it by following steps.
How to Disable Haptic Feedback on iPhone 7/ 7 Plus: Fresh Home button
