Not a new feature but a feature that should return from the first game. I really miss my pumps and pipes (https://subnautica.fandom.com/wiki/Pipes_(Subnautica) to get oxygen to places. I don’t know about you, but I used this a lot on the beginning of the game before getting a rebreather and even after getting the rebreather I often used this help me get further down than my air tank would have allowed otherwise.
Maybe if you find the time you could bring it back

i think on its own it is too niche and we have better alternatives like the oxygen generator - which also no one uses. after reaching the tadpole, it all beomes obsolete and sadly irrelevant.
i was thinking how to make such equipment more useful. but without at least a game mode where oxygen is made more relevant, it tough: https://subnautica2.nolt.io/10069 - the pipes would make a lot of sesne, if bases required oxygen.
