I can totally understand changing the behaviour - it IS silly that one has to press the shift key to change the size of a photo without messing up the proportions - it was ALWAYS a silly thing in the interface, because you almost never want to change the proportions of the image.
However, it's equally, or even more silly not to change it in ALL Adobe apps and situations. Yeah - Adobe is insane and I'm peddling away as fast as I can, these days.
BTW - all Affinity applications (Publisher, Photo and AFAIK, Designer) use the more sensible click with no shift required to resize images/objects. But they're consistent about it.
