For a time-shared multi-user operating system - Yes. In fact, not only should a multi-user operating system protect against incompetent/ignorant programmers, it needs to protect against malicious/ evil/destructive ones too, those which are bent on the system's downfall. Unix definitely falls into this category. AmigaDOS does not; it's a single user PC and single user OS, and that's why I think lack of resource tracking and memory protection is not gross negligence, just a reasonable design compromise. Memory protection is expensive - the cost of an MMU. Resource tracking probably should have been there, and in fact CAOS (the original, undelivered Amiga OS) had it, but Amiga had to abandon that and use Tripos instead.
