You are choosing to focus on the "premature optimization" wording, which is fair, it was said. I'm focusing on "as a community would we choose to reimplement and universally adopt this optimization?" (emphasis mine). I think it would be implemented, I do not know of any evidence that makes me believe it would become universally adopted given modern resources.
I'm not sure exactly what was originally meant, I interpreted it as how currently dynamic linking is the norm, is used in every mainstream OS and most the applications run on them, and all the major mobile platforms. If we had to make a choice right now without the history of dynamic linking behind us, would we still choose to use it for the majority of platforms?
