What’s missing in his point and examples about “performance isn’t everything” (aria properties, forEach, …) is that these are cases where you could optimize later when and if needed. Using forEach is a fluid coding choice at the time but if for any reason you need to optimize to a for loop you can with minimal fanfare. But buying into web components is more of a one-way door and harder to iterate optimizations, and that’s the problem.
