I don’t know if this was issue before 2015, but I really noticed it on an edit today.
When you are copying and pasting attributes of a file, it doesn’t paste size correctly if you have unselected uniform scale. I have clips that are a strange aspect ratio so I have to scale the height and width separately, and the only way to paste the attributes correctly is to first unselect uniform scale, and the paste works as you would think. this is frustrating with many clips, and uniform scale should be one of the attributes that Adobe copies when you copy and paste them, but it is not.
