Garbage collection isn’t absolutely necessary with lifetime/liveness or explicit frees. Furthermore, at scale in production, if a GC were absolutely necessary, then it’s vital to have a concurrent, incremental collector like c4 because GC 30 sec pauses and sharding up app servers with 2 GiB heaps is unacceptable in the real world.
