    Evolutionary, I’d expect it’s because drinking saltwater is generally counter productive.

    If you are on a raft without water, you will die faster id you drink the salty sea water than if you don’t.

    Drinking lots of slightly salty water, will put stress on your kidneys, as fresh water is the remedy to compensate if you got too much salt.

    That’s the evolutionary perspective, but how the mechanics work for the body to detect it IDK. You can have watery sauce or soup that is salty but taste great, despite being mostly water. So I think there is a bit of what’s expected involved. We generally don’t expect water to be salt.
