Shifter excessive shake & rattle question

First, if you're going to take a video to show minor shaking, you might want to stabilize the camera properly next time.

Second, that looks completely normal to me. I can actually make the knob move noticeably forward and backward on demand. That's in addition to the side-to-side vibration from the drivetrain. And a 480 gram shift knob
