Regarding the "...", I would advocate against the use of more
variant-parameter functions.  There are already several of them, notably all
of the JS_*Arguments functions.  Other languages may not support this
(Delphi/Object Pascal is one of them) and this could be a very crucial API.

If it's important to have the "...", then perhaps I can work up a Delphi
routine to append (prepend?) arguments to the call stack.  I'm not sure
exactly how C implements it, but the info is probably out there.
