In practice, binary size does not matter much for most use cases. (But for embedded and demo scene this is important) It is a simple proxy/heuristic for the level of bloat / crust / overengineering of the runtime and to the quality of the compiler. If a language / framework can't do an extremely simple task in an almost optimal fashion, then it is unlikely that it will improve with more difficult tasks. It is like looking at the CPU/GPU load of an app in idle mode.
