Your particular point could be solved by an optionally overridable delay on responses. I agree that optimizing for "respond to all things promptly" could lead to what you're saying. That doesn't need to be what you're optimizing for, solely. If being good at email brings more high value email, well, that's one of those good problems maybe. If it brings more low value email, treat the low value email differently. Or rather, treat all email as what it is. I'm not saying there's no place at all for purposefully delayed responses.
