Nice changeset! I straightened out the corners of the buildings here in this changeset: https://www.openstreetmap.org/changeset/152470098
If you use the ID editor you can straighten corners of an area by pressing the Q button when the area is selected. 

In which aerial imagery did you see the outlines? I struggle to find any good imagery, this is a very new development after all.
