Yeah, it gives no benefit except making the game more realistic.
Playing the game, I was under impression that realistic feel is your goal.
Most of the time the game gives me Super Metroid vibes. Grim setting, the feeling of some unknown dangers waiting around the corner. I love it!
And then... Hop! The immersion breaks. Each of those silly pull-jumps yanks me out of this grim world into the realm of cartoon.
"Not very high on the list" is a perfect position for this issue as long as it actually is on the list.
tl;dr
Mechanically there's basically no difference.
Thematically it's a difference between full immersion and occasionally breaking it.
