   That could easily be written as:

   var promiseB = promiseA.constructor(function(resolver){
     promiseA.then(resolver.fulfill, resolver.reject, function(val){
       resolver.progress(0);
       resolver.progress(1);
     });
   });

   And of course libraries could provide a utility methods for that abstraction.

   True, but that requires breaking your nice clean chain of thens.

   The OP idea seems a bit unwise given that you could do setTimeout(prop, 50, 100);
