Who needs throughput? Server software, but Linux is already dominant there and everyone's happy. For everything else, including desktop and mobile operating systems realtime sounds like a good idea.

Though in practice, the act of designing your code for realtime tends to produce better performance than the status quo of doing nothing. Most uses of this warning seem intended to promote the latter rather than to get people thinking about their actual requirements.
