Something I have noticed about Fowler-esque / Uncle Bob-esque codebases is that usually only the guys who wrote it understand how it works. Which is either a blessing or a curse depending on whether you wrote the thing yourself or somebody else did it. And it also seems to defy the point of "making it easy to swap implementations by writing a ton of interfaces".
