Absolutely. This is why it's so important to have input from engineering during the product design stage of any new product or feature: good engineers can help spot when a minor change to the requirements could have a major positive effect on the overall system complexity and time to delivery.
Value scales exponentially with good design, costs scale exponentially with bad design.
This is the hardest thing to communicate to people running projects, in terms of why the amount of Python or Django or whatever that you know has very little to do with being a good or bad developer.
