Then the documentation should be fixed also. I can't imagine a 
situation where it would be useful to associate nan with any kind 
of truth. Change the spec to
"Fundamental types are true if they are valid and non-zero."

And wasn't the whole idea of editions to be able to make breaking 
changes? If you don't like the changes, you can stay with the 
current behavior.

And I consider integer-propagation a feature worthy of being 
dropped. And unary operators changing the type of its operand is 
part of this "feature".
