         The only thing that I could see JPEG being used for, which   
isn't noted in your format description, is as a "preview" or   
"thumbnail" image.  It may also be worthwhile to have it as a "fully   
composited" image - ala Photoshop - for applications that don't have   
all the tools for composite on the fly but want to display the image.

Actually, I think jpegs for the actual raster data in some cases is perfectly fine.  
  
Use case 1: I have this jpeg 8MPixel photo, I just want to add some text to. Why  
should I make my file 3 times bigger, if all I need with noiseless precision is the  
text layer ?   
  
Jpegs should not be the default pixel storage method, but I can't see why not to  
have fully functional jpeg layers.
