Yep. I remember spending a day trying to genericize a Rules Engine type system in C# and finally realized it was idiotic and made the code more complicated, and we'd probably only ever use the code exactly how it was now (i.e. not generic), and so I left it as-is (and to my knowledge, yes, it stayed exactly the same for forever). I see the same tendencies in many programmers - "hey, I want to write this once and cover every single case that could ever come up"... even when they really only need to solve one specific problem, and making the solution more generic makes the code a lot more complicated than it needs to be for the specific problem you're solving.
