This is true, but as long as a few big browsers implement e.g.  
preload="none" in a somewhat compatible way, it's hard to imagine page  
authors not coming to depend on that behavior so that it becomes required  
for web compat. It would be interesting to know if there are  
counter-examples, any script-visible behavior that is allowed to vary  
greatly between implementations without causing scripts to break.
