No, I believe it's just a recommendation, but Ford's verbiage is a bit funky:

Then point #3:

- Reduced fuel economy.
- Reduced brake performance.
We recommend Motorcraft® motor oil for your vehicle.If Motorcraft® oil is not available, use motor oils of the recommended viscosity grade that meet API SN requirements and display the API Certification Mark for gasoline engines. Do not use oil labeled with API SN service category unless the label also displays the API certification mark.
To me, it reads like they want you to use Motorcraft or an oil that meets the WSS-M2C946-B1 specification. If that isn't available, you can use SN. However, IF that causes damage, and it doesn't meet the specification, your warranty may not cover it
I think in this case, to play it safe, I'd use an oil that carries the specification, of which there are myriad.
To me it straight forward
We recommend Motorcraft® motor oil for your vehicle.If Motorcraft® oil is not available, use motor oils of the recommended viscosity grade that meet API SN requirements and display the API Certification Mark for gasoline engines. Do not use oil labeled with API SN service category unless the label also displays the API certification mark.

An oil that displays this symbol conforms to current engine, emission system and fuel economy performance standards of ILSAC.
I think you are letting your SuperTech bias show through. Ford has a certification standard they want you to use. If you use something else, that follows another standard and your engine blows because of an oil related issue, they don't have to honor you warranty.
