Adding Salt To Pool Without SWCG

Good Morning All...

Just wondering if there is any benefit or danger to adding pool salt to my 18'X36' inground pool? Would it make the water a bit less harsh (i.e. softer)? From all I've read, the cost versus the benefit of installing a SWCG don't seem to make a whole lot of sense, given I have zero issue maintaining my pool with chlorine, Borax, and baking soda. That said, I've often thought about dumping in some pool salt, but I'm not entirely sure what the benefit would be or if there is a chance of causing any damage to anything (i.e. my underwater light, the liner, etc)? I would welcome any and all feedback. Thank you.

I also forgot to mention my Dolphin M5 Robot? Would adding salt adversely affect the robot at all? I assume the added salt wouldn't magically turn into chlorine, without a SWCG, correct? Sorry for the elementary questions. I'm just trying to figure all of this out.
