Im not going to agree with you on this.The Raptor is a halo product, that’s why it gets the 3.5 HO that is not available on any other F-150 except the 19/20 Limited. It would make no sense to offer the 5.0 that has less power, less torque, and worse fuel economy. The Roush packages are entirely aftermarket and not compatible with the factory powertrain warranty, which is why Roush includes their own separate 3yr/36k powertrain warranty. If the engine or transmission blows at 36,100 miles, you’re on your own.
1) Ford needs to add the 5.0 L HO version to the raptor. Its actually kind of sad it isn't here already. 450 HP on the 3.5 HO is the base engine. 5.0L HO could bump that to 500 HP and it can cost a 3 to 4k $ more option. That way you get the V8 sound that everyone has been wanting.
There is a difference in the customer wanting a V8. There is the pool of people that want the power from the 5.2L, and there is the pool of people that want the NA V8 sound. Also to be honest, the way they are making the 5.2L, it's probably going to be bundled in such a way that, it's just not going to be worth it for the people that only want the sound of the v8. They are probably going to make you get the 801A high package, make you get the 37 package, then you can add the 5.2L engine, and that's probably also another 10 to 15k...
2) If they weren't so greedy, they would add this 5.0L HO, it would bridge the gap between the 3.5L and the 5.2L. AND IT WOULD SELL LIKE PANCAKES.
Also, ford performance came out with their version of the supercharger addon that can installed at a ford dealer on the 5.0L... I'm sure they can make another model of this to fit the HO of the 5.0L. And if someone wants more power 1 to 2 years later after owning the normal V8, they can go get that installed, instead of buying a halo product 5.2L and being shoehorned into the 801A high package, and the 37 package. This also fixes the warranty issue you described.
Instead they are too greedy, and not adding the 5.0L to the raptor, just to sell the 5.2L version with outrageous profit margins. Thats the truth, this isnt an engineering problem with the vehicle or in-capability. This is greed.
