This package is intended partially to allow someone who is not familiar with ELisp to just drop a file they downloaded into a directory and have Emacs load it. The benefit of providing a package to implement this functionality is that the user of the package does not need to figure out how to define dir themselves, it provides error handling so that Emacs initialization will not be interrupted while loading the files in the load dir, it optionally supports loading files recursively, and supports loading of byte compiled files. To support all of that your two lines quickly grows to be considerably more. My current implementation has about 100 lines if you strip out the comments.
