A fashionable framework on your CV will get you an interview, while claiming that the code was simple won't. It's as immoral as objective reality is.
Reminds me of the anecdote about Bill Atkinson: His manager required a "productivity" form that asked "how many lines of code did you write this week?" Having just refactored QuickDraw, with vast gains in speed and simplicity, answered "-2000."
