Then IDEs could propose one of these operators. Looks like an advantage 
to me.

Another potential issue with the language proposal is that compareTo is 
potentially somewhat less efficient than less general methods. For 
instance String.equals implementations can quickly determine that the 
argument is different through hash code and length. Computing compareTo 
could be much slower.
