A dead SSD should mean a simple replacement of the SSD, not the entire board. Soldering the SSD to the board makes this recovery tool and the "port to nowhere" necessary. Also it eliminates the possibility of upgrading your SSD down the road.
Yes, there are tradeoffs, but when the entire world is demanding thinner Macbook Pros, they have to draw a line in the sand somewhere. We all have to suffer with non-upgradable stuff, but that apparently is the price to pay. I mean, we're not barbarians. We wouldn't want to sit around with a macbook pro that was thicker than 131 millimeters. It's downright embarrassing.
"Hey Johnson! I notice your laptop is 131mm thick! That is important to me, an executive! You work here?! Double plus good!"
"Yessir! Don't worry, though, it gets less than 5 hours of battery, and I assume the SSD will never fail, because Time Machine only works half the time!"
