Go in Production

This is a myth. Garbage collection changes what you worry about. For small, short-lived programs you don't have to worry at all whether garbage collected or not (because you can just abandon the heap when you exit).

For long-running programs you either worry about freeing memory, or you worry about not making too much garbage. What you save with garbage collection is the problem of worrying about memory in programs that don't need to use that much memory (i.e. you eliminate memory leaks). If a program uses a significant amount of memory over a period of time that garbage collected or not you worry about memory.
