You say a lot of work for little reward, but the cost of them giving a big "fuck you" to WP7 early adopters is a much higher cost than the salaries required to pay programmers/managers to port WP8 to WP7 hardware. Why would anyone buy a WP8 device after this debacle? They basically killed WP8 before it even started. In order for WP8 to succeed, they need early adopters and loyalists to evangelise WP for them for free. They've killed any loyalty anyone might've had for the WP platform. These users will ditch WP when their contract expires and tell all their friends and family members to buy Android or iPhone. As I see it, MS has only two choices to save their WP platform: priperly port WP8 to WP7 hardware, or give WP7 users free WP8 phones.
