This requires that the compiler actually create a second StringBuilder. 
  This is not efficient.  What Roedy is saying is that given an existing 
StringBuilder object, he wants to be able to invoke multiple #append() 
calls with out having to spell out each one.

This is a point.  I think that the varagrs method might be notably 
inefficient in many cases, as primitives would be autoboxed.  However, 
it would not hurt to actually investigate this and determine how much 
and how often the autoboxing becomes an issue.  That investigation I'll 
leave to the concerned parties, however.
