While package management is a solved problem in Linux, I imagine they want to keep the coffee as similar as possible between Windows, Mac and Linux, and cross platform packaging is certainly an entirely unsolved problem. Also in steam it is traditional for games to just have a directory to themselves. Getting them to install things in the right place would be more work, and opens up risks from badly packaged games.
