All the above; but they are closely related.

If the program has too many lines of code, it tends to be not too well organised (because it usually means it does too much) and it usually means it has too much features (thay could be easily moved into separate programs).

    > I can easily just ignore the features
    > I don't use (the vast majority)

Please excuse my blasphemous comparison, but how this is different from how people use MS Word? :)
