Indeed. Why don't you bring this up on a Scratch forum?

The VM was changed to not kill the image but send it a close event.  
John said he would handle that event in the next Scratch release. I  
pointed him to the relevant changeset from the Etoys image:

The other platforms' VMs were changed, too, although there the new  
behavior is optional.

The problem on X11 always was that it was too simple to accidentally  
quit Squeak. There was no confirmation dialog as on Windows, or a  
specific menu item as on the Mac. So I find the new behavior much safer.

Some Scratch versions do have a quit button ...
