This is 2016 and devices have more memory, that's true. But ignoring memory efficiency is ignoring the basic principle of engineering and I see younger folks tend to ignore that more than olders. Having more memory available does not mean that reduced footprints are not better.
Sure, but I'm also not going to optimize dev dependencies. I care about the prod environment, but when one window of my IDE takes up 4x the memory of the app I'm actually developing, I just fail to find a reason to care about my local environment.
