I wonder if it's technically useful or if it's a commercial move. I have an Ideapad Y470 (a model from 3 years ago), and I got the impression they tried to limit the RAM below what the hardware could run, maybe because they want to segment the market in a certain way. The customization page on their website only allowed 8GB of memory and the user manual explicitly stated that the maximum RAM was 8GB. I bought 16GB after reading users reporting that it worked fine, and I can confirm: it works fine. I push it to the limit all the time. Then again, it might just be that new RAM chips came out after the laptop did, and I might just be conspiracy-theorizing.

This is the logic board on the 2014 15" rMBP: https://d3nevzfk7ii3be.cloudfront.net/igi/PmBmFGBkmnHDvEpo.huge https://d3nevzfk7ii3be.cloudfront.net/igi/PmBmFGBkmnHDvEpo.h.... It's wedged between the fans and the batteries, and there's memory on both sides. If you make the board larger to put in SO-DIMM slots, you lose either battery or cooling capacity. The rMBP manages to fit a 15.4" screen and a 95Whr battery in 4.5 pounds. I've never seen an upgradable laptop that fits that much battery into that weight class.
