No, and here is why
The reason is that the phone can power on accidentally in your pocket or bag very easily.
If that happens, then any additional bumps activate apps, etc.
Also, while there is a display time out of 1 or more minutes, the lock screen timeout is much shorter; 5 seconds to dim, then off after 10 seconds.
This saves battery life, because accidental bumps that activated the phone only turn on the screen briefly. Otherwise, if the power button is bumped in your bag or pocket, the display will be on and active for at least 60 seconds each time, with any touches resetting the timer for another 60 seconds minimum.
Anything that bumped the power button is likely to keep occurring and keep the display turned on and the phone fully active.
Without the swipe gesture, the battery would be drained quickly just from being moved around.
