No more so than any "new" image format, such as gradients (not that  
layered image formats like Photoshop files, TIFF, etc., are  
particularly new). If it used an existing multi-frame (rather than  
multi-layer) format, such as animated GIF, then it could be set to  
repeat zero times and only show the first frame.

If it was something newer, like animated PNG, or multi-layer PNG, then  
it might be even better, showing up as the first layer/frame in UAs  
that didn't support it, and editable via some sort of plug-in for  
PhotoShop.
