Show me a concrete example. Also, there is no "picking" of which 
interface method is implemented. Both are implemented by the same 
method.

I agree. I was surprised as well when I first learned about this, 
but that doesn't mean it's incorrect.

There's this other language called Java that you may have heard 
of, that does things the exact same way, and the many millions of 
programmers that use that language seem to have no issue with 
this behaviour. I've already agreed that it would be worth having 
a way to write a different implementation for different 
interfaces with the same method, but that is the very 
*definition* of an enhancement.
