Does that document means that future javascript proxy implementations would not have Proxy.createFunction
and I will not be able to create a proxy which could be called as a function?

The Reflect object is a single ordinary object.
The value of the [[Prototype]] internal slot of the Reflect object is the standard built-in Object prototype object (19.1.3).
The Reflect object is not a function object. It does not have a [[Construct]] internal method; it is not possible to use the Reflect object as a constructor with the new operator. The Reflect object also does not have a [[Call]] internal method; it is not possible to invoke the Reflect object as a function.
