I didn't follow the beginning of this thread and didn't test this 
specifically, but my understanding is that the behavior didn't change 
between 3.6 and 4.0 with respect to this.  i.e. if you have a 3.6 script 
that was setting classes dynamically then it should continue to work 
with 4.0 once you adapt it to work with styles.

BTW, it is ok to reuse and modify the same class multiple times as long 
as you TURN OFF the label cache.  If you leave the label cache enabled 
then you cannot modify a class until the shapes (labels) in the cache 
that use it have been drawn/flushed from the cache.
