yes it would but it was used when you werent around ships to detect you or if they already had you located you might use it to sit on the bottom without "hitting" it and sinking yourself
it wasnt done willy nilly and think of it like surfacing, you make sure its safe before you do it like in setting up an attack, before the enemy is in range, you locate where the bottom is so if you need to go deep to evade after the attack you know your limits
