The modification of a copy instead of the real file to prevent data  
loss in case of failure while editing is a savety feature no one would  
dare to remove. I don't think gimp does otherwise.

It's just that the modified copy can replace the old file, leading to  
a new independent copy, or the content of the modified copy can be  
written (as a whole) into the old file. This would preserve the  
hardlink and modify all linked files.
Nevertheless it would be a short atomic action at the end of the  
editing preventing data loss.

If saving a whole image is to time consuming, you can of course make a  
diff of old and new file and then alter the original file. This would  
lead to even shorter 'dangerous' write time.

But, again, I'm not a developer. I'm not even a user yet....
