I am nervous this means Apple will hold back features from iOS to get people to buy an iPad. For example, they announced the new Files app with iPadOS but there is no reason that shouldn't all be available on an iPhone.
iPhone doesn’t have a screen large enough or a USB connector…how would you use the “new Files app”?
Pixel 3A comes with a USB C to A (female) adapter in the box which makes it seem like this kind of thing is going mainstream.
