That means that all but the last return value is ignored.  Why is the 
last return value any more important than the earlier ones?

ISTM it would make just as much sense to do

   def chain(*iterables):
       values = []
       for it in iterables:
           values.append(yield from it)
       return values

But I don't see any point in changing the current behaviour.
