I wouldn't say "not worthwhile", but the variadic support would be 
minimal unless large chunks of the API are designed for it.  What I 
noticed when writing Chaos is that to really get the benefits of 
variadics, you need to alter the a lot of stuff.  Specifically, in how 
it relates to compatibility, you need to alter parameter orders all over 
the place since the set of variadic arguments are always the last.
