One angle that's missing from this discussion: the cost asymmetry. The effort to do this well is disproportionate to the effort to do it poorly, which means most implementations in the wild are mediocre. That creates a weird market dynamic where quality becomes the differentiator by default — not because it's hard to build, but because most people stop at 'good enough' too early.
