Awareness of the layout and size of data is still very common in game development. Mike Acton did a great talk related to this at CppCon a few years ago : https://www.youtube.com/watch?v=rX0ItVEVjHc

This is true for high performance server software, too, especially servers that resemble databases.

I personally find myself thinking about alignment more than I probably should. For Go, I use http://golang-sizeof.tips for experimenting. I've been able to make schema changes to my structs to enable more functionality without increasing memory usage.
