The entirety of the Super Mario Bros video game was just 31kb, almost 20 times smaller than the total transfer needed to load the YCombinator home page, so I'd argue that's not a great heuristic for performance or efficiency, especially given that processor speed, network bandwidth, and most importantly storage has increased exponentially over time. And conversely, it has never been easier for a single developer to quickly write complex applications that can be deployed to multiple operating systems at scale around the world. It's important to weigh the cost with the benefit.
