I think it is (used to be?) a common pattern.
Tom Cargill took a year off from Bell Labs Research to work in
development. He joined a group where every subsystem's code was printed in
a separate binder and stored on a shelf in each office. Tom discovered that
one of those subsystems was almost completely redundant, as most its
services were implemented elsewhere. So he spent a few months making it
completely redundant. He deleted 15,000 lines of code. When he was done, he
removed an entire binder from everybody's shelf. His coworkers loved it.
During his performance review, he learned that management had a metric for
productivity: lines of code. Tom had negative productivity. In fact,
because he was so successful, his entire group had negative productivity.
He returned to Research with his tail between his legs.
Was this vignette in, "The Practice of Programming"? I know I've read it
somewhere before, either there, or in the first edition of "Programming
Pearls."
In the latter, Bentley makes a quip about incentives and lives of code.
Basically, if one incentivizes repetitive code, that's one what gets; "if
you pay by the line of code, how do you think an array with 500 elements
gets initialized?"
