It could. But it is a bad idea because

1. Because that does not mean anything in most langauges of the world.
2. Because you are unlikely to come up with a complete text string that  
people always emit correctly, and get it implemented through the various  
tool chains in use, with anything like the same efficiency as working out  
what the lack of an alt attribute means.
3. Because it isn't actually a terribly helpful statement for a person to  
hear multiple times.
4. It means that all legacy testing systems will have to be rebuilt to  
ensure that they recognise this magic string as being equivalent to not  
having any alt attribute.
