I find myself trending the same way, but for another reason. I've gone back and forth on my viewpoint over my programming career, and now whenever I decide to revisit an old project, I find the "more NIH" I wrote it the more likely it is that I can load it up in a current version of the compiler / IDE and hit "Build and Run" and it will Just Work. Even if I included the external library in the repository, the library still contains extra code I don't need which may fail to build.
