It is possible that the C standards authors here were envisaging other 
types of explicit conversion in the future.   For example, C++ has 
multiple forms of explicit conversion, at least some of which could 
reasonably be copied into C (such as the functional notation explicit 
type conversions - "int(x)", meaning the same as the cast "(int) x").

You could argue that the C standards use the term "explicit conversion" 
to make it clear that there are no /implicit/ conversions involved.  It 
does not matter if the explicit conversion is done with a cast operator, 
or in some other way - even if C (currently) has no other way to achieve 
the effect.
