You need that living habitate to survive 6 months in 0g minimum, plus move it planetside without breaking anything.
You could expand the habitate to a larger area later, true, but there’s still like 7 mass cycles that need to be maintained long term, and this system needs to be robust enough to trust a few dozen people to. Otherwise, it’s just an extension of Earth’s biosphere and is dependent on regular resupply.





Memory leaks are often difficult to deal with, and many contemporary languages basically encourage them. I know many applications that suffer significant performance issues due to memory leaks, and way too many that simply don’t care about memory footprint.
A language that treats memory management differently from the start makes all these problems much easier to deal with, if they appear at all. The real question is if the other costs of using the language are worth the somewhat niche performance gains.
