😁: Starting to use the ConcentricRectangle APIs in Beta 4. They are much richer than I thought they might be, with per corner customization and uniformity controls. I really like how flexible they are, I'd worried we'd just get a "one size fits all" approach.
🙁: They don't seem to currently work correctly in SwiftUI sheets (which is where I need them most), the radius is too small compared to when the same shape is shown in the root view hierarchy. Hopefully just a transient bug…FB19020152
