>If an engineer is frustrated at the responsiveness of an ‘Add to cart’ button click during development, then they’re probably more likely to investigate why and resolve it. IMO this should be in QA/SDET's realm (ideally via automated testing). If you're rich maybe you have one or a few SWEs devoted to performance. This will force other people within the company to also think about these metrics. Don't be a siloed developer quietly fixing all of these things for free just because it's slow on your machine.
