Is it? OS are general-purpose system, it's always been the case that applications being known workload they had better knowledge of what they need (it just doesn't matter to most of them). That's why you can tune your db configuration, or you can police individual processes using various tunables, or you can ship your program with a better allocator than f'ng glibc malloc. And a modern browser is a pretty complicated process manager, the OS has no understanding of what the various processes do or what state they're in.
