Saying that a certain project exists that does not use newer features of a language does not detract from the fact that the language itself is much more featureful. Im sure I could find popular projects in every language in the world which only uses old library functions and hasnt been updated. I would hazzard a guess that as node changes so frequently, there are untold amounts of projects still using old inefficient methods compared to what is available in the latest version
