Empathy is the actual mechanism for how those other things (quality, etc) are achieved. Diversity helps empathy (represent the user and relate to them better).

Another way to extend the analogy is its a standard management technique when provided with something you don't want to do, set up an isolated team with no deliverables, no authority, and no direct reports. Ta Da we got us "quality" or "diversity" or "Dev Ops" and we didn't have to change anything.
