I think grep is a compelling example of when it makes sense to do the extra work here. But I'm more dubious of the idea that carefully optimising yes was a good use of engineering time.
There's an opportunity cost. There has to have been a better use of that person's time than taking a tool designed to say yes to repetitive "are you sure?" prompts, and get it to keep up with memory throughput. The throughput of a tool like that does not matter.

I literally can make no sense of that. Why do you think widely used pieces of software should not be well made.
