Hi,

Several reasons. The scene copy function is very primitive, which  
doesn't reliable make full copies. Further that then only works when  
you hack in low level datastructure calls in Blender. Is all too much  
risk and work for now.

The main advantage of a file-save undo is that there's no hacking  
needed, using existing functionality. On my slow 450 Mhz mac, files up  
to 5 meg work very interactive still. Over 20 meg it becomes a pain yes.

Since we're in after-release time, I want to use this period for  
feedback. I also have ideas to solve certain issues, like saving  
partial files for example.

The current code is incredible short & clean, easy to support, and can  
also be removed simply.
