I honestly think the salt making change is not good with the oceans' current iteration. I do believe oceans are off by default on land generation, and a player that just made a world without looking into the ocean settings would be locked out of the salt making aspect of the mod.
This caused me great confusion as I looked for an ocean to get some salt water, only to get out and take a peek at the ocean settings on a default survival world to see they're off.
