I'm surprised you've never heard of Ford oil pans rusting out. I live in NH, and its very common in ME, NH, VT, etc. Ask the 7.3L diesel guys how they feel about it...requires major work to replace it because of an x-member. Even older Ford trucks from the 1980's and 1990's had this problem. The oil pans are very thin stamped steel and won't provide any meaningful impact resistance either.
Ugh.....Oil leak

Yea, I have a lot of friends with Superduties and F150s- not one has ever had a rusted oil pan. Everything else possible has rusted though- radiator supports, rockers, cab corners, cab supports, bed supports, fenders, beds, bumpers, exhaust, window channels, spare tire carriers, hitches, you name it. Not a single oil pan failure. I always wipe the oil pan around the bolt after a change, then wipe the pan with the oily rag. I'm sure that's helped my trucks over the years.
I've also seen quite a few steel pans that were dented by road debris. They took a hit, held the oil and remained usable for the life of the truck. A plastic or aluminum pan likely would have cracked. Maybe not though, stuff like that is pretty random depending on what was hit.
Of all three materials, I would still prefer aluminum. It has most of the advantages of steel, won't rust, and is very good at dissipating heat. They are also thicker than steel, which gives you a much stiffer and flatter gasket surface where it meets the block. A plastic pan seems to me like it would have much more flex in the gasket surface, more similar to a steel pan. Aluminum castings are the most expensive option for the OEMs though, so they probably try to avoid them and go with plastic or steel where they can.

User formerly known as sasquatch77 is not wrong in this case. The plastic pan in use on the Rap - maybe the rest of the EB lineup --is-- being reported as failing at an abnormally high rate even accounting for the “only posting bad news on the internet” phenomenon.
A buddy of mine did find an aluminum EB pan, and sent me a link to it, I didn’t follow up on it but... something is not right with this implementation, whether it’s the pan, the installation or a combination, we shouldn’t be seeing this many issues.

Widely reported leaks are not caused by cracked plastic, but a poor seal. Metal pans also require seals, so this problem wouldn't be solved by changing what the oil pan is made of.
There is zero stress placed on the oil pan, so it makes a lot of sense to make it out of something that is cheap, lightweight, and doesn't corrode.
This is an incorrect statement.. pans are being replaced and get new gaskets (gaskets are 1 time use). The leaks shown on the web are around bolt holes where the bolts seem to have been overtourqued. Steel pans never had issues like these.
It could make a difference. The stiffness of the pan rail matters. The clamp load is not even since the bolts are spaced apart, so the stiffer the rail is, the less likely it is to leak.
My guess is they designed the plastic pan reinforcing ribs assuming certain performance from the gasket, but the gasket is not performing as assumed, therefore they are getting leaks.

Just completed the oil pan replacement. The leaks are caused because the factory did not add an adequate amount of the“liguid” gasket.. there is no gasket, all there is an RTV caulking substance added to the pan. My tech used the one used on Diesel engines which dries faster and creates a better seal than what is used in the F150... if you look at the first two pics, you can see how thin the rtv caulking is...here are the pics:

Poster who actually owns a G2 raptor and had a leaking oil pan disagrees with you, (and has pictures to prove it) but nothing is new since everyone on this forum disagrees with you.
