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.
