>who said this is something that is necessary at all stages?

understanding when you don't need to measure is important too. If you are just making a small 2d app as a hobby with no more than maybe 100 draw calls on hardware that exceeds that of a potato: I probably won't waste much time with optimization schemes and just crank something out.

But that same app may want to be kept as small as it feels so I would focus more on any assets being compressed.

I took it as testing. Unable to understand what you're trying to solve, frequency of usage for such functions/modules, the amount of reach your code will have (only used once in a small module? Code code that he core multiple layers up will rely on?) and not considering potential edge cases. More or less similar to what you said.
