It's a small skip, but I thought it was interesting and it is indeed RTA viable as this video was done RTA. It skips having to fight a couple waves of enemies and then having to flip the switch to turn off the gas to gain access to the next room. It does save time if you line it up quickly and you could probably dive along the ceiling instead of walking along it for extra speed. For reference, my world record 29:07 run takes 58 seconds to complete these two rooms, while the video below with the skip does it in 48 seconds, so it saves at least 10 seconds.
