It seems there is one use case that would be viable.
If we use the water at depth.
I think the way to go is underwater living pods.
If we go this route, I propose we also kickoff a solid Merpeople program (Mermaids, Merman, etc). The goal woukd be to gradually move the human race to be Merpeople. One day we will be viewed as the Neanderthals and Merpeople the people. As everyone knows, the hallmark of any reputable Merpeople program I'd breathing underwater, indefinitely, in Salt water. If we've been able to achieve that it's reasonable to assume we'd also be able to engineer the ability to "drink" seawater directly.
All this to say, I guess there isn't really an application for this.

We need way more daylight than most people realise, look at what goes into a submarine who are already living in a what is effectively a cramped mobile blacked out cave.
Living under water in pods has been done before but damp was the biggest issue from what I remember.
Excellent points. We need to add living without nearly as much sunlight, and living in damp or submerged environments to the goals of our Merpeople program.
I'd imagine there are stepping stones along the way. We won't make it all the way to fish people right away, we'll likely have amphibian people first. Those people, amphibian people, should be pretty good in living in damp environments.
