That’s why they put in the “debatably” part. Anyone can debate to their heart’s content that it is superior. And they’d still be wrong.
(To be clear, I’m agreeing, you and Kolanaki are exactly right.)
But it doesn’t even matter if it’s superior. There is value in seeing the steps of progress made to get to a superior edition. This is why we have version control for code. It’s not always just so you can do a revert or see the latest change, if it was we could just throw away commits older than a month or something. It’s valuable to be able to see the whole history. We can still learn from it and appreciate what it did for its time, even if it’s old.
Ocean salinity varies slightly but averages around 3.5%. Brackish water would be less than 3% as long as it’s saltier than freshwater, which is limited to 0.05%. Brine, which OP is asking for, is water with 5% or greater salinity. The ocean doesn’t get that high but salt lakes definitely can, the Dead Sea is almost 35% salinity. Also why it’s called the “Dead” sea, FWIW. Maybe you could pickle stuff there.
