I figure it’s probably for convenience or just how you like to do things in your workflow 
I don’t actually remember if I moved it. Looking at it now, it seems a bit illogical that rotation and crop are separated by the exposure, although I’m already used to it.
Happy new year!
Az the bottom of the right panel, you can check the module order. If it’s not ‘custom’, you didn’t move it. You can reset the order by selecting raw 5.0 (I’m not at my computer, cannot check).
Thanks, I got “v5.0 RAW” there.
I think and my brain is foggy today so this could be bunk but you can sample outside crop I believe for say cloning or retouch so maybe having tone and exposure after the crop might change how that works… but this could be my clouded new year thinking… I’m sure the discussion around the module on GitHub when it was reworked would possibly explain the position
I believe you are correct, to make it easy to clone/retouch/liquify etc, you want to operate those modules after rotate/perspective shifts. Crop coming after those modules means you can use the whole frame to sample from for retouch et al.
You always bring clarity to my fog 
Happy New Year
