Why should everybody pay for it?

Why? Monocultures are often a bad thing.

That's not true in any case. If checking for an implemented interface 
was sufficient, then the interface would have to look like a Java 
interface or something similar. The questionable feature that you are 
asking for implies IMHO a lot more changes than we all see now. And I 
cannot see a real benefit.
