I was thinking that, since it uses the intended mechanic of gaining height when jumping near a corner, the water space jump is not a glitch, but an exploit, and thanks to the Metroid Dread Speedrunning Discord Server, I was able to pull this off, without water bomb jumps. It will be very useful in Any% Glitchless.
P. S. ignore the fact that I'm using the screw attack: it doesn't change anything.
