A lot of people talking about correctness and performance, but I have a suspicion that most limits in older software had less to do with that and more to do with the fact that things were written in C, where arrays whose size is not known at compile time are just a lot more work for the programmer. There are cases where the allocations and memcpys when a Go or Java collection grows can be a real problem, but the vast majority of the time it works out fine to leave the size unspecified.
