Here's the problem: we're also constantly adding code that needs to be written, reviewed, tested, and maintained. We're talking about a small amount of code here in this particular example, but then again, what particular straw broke the camel's back?

I think we have to be aware of runtime overhead where it matters most: in hot loops, or where something is instantiated tens of thousands of times. In all other cases, focusing on bytes and nanoseconds can actually be detrimental in the long run. It makes code inherently harder to reason about, and when many such "optimizations" are taken together, we can end up with code that you can't change any more for fear of breaking the myriads of code paths.
