Review comment:
       I think this will be overkill as well and not necessary. Basically, I am 
looking the context as controller's output and reacting on output is not ideal 
from my prospective. Also, unlike regular resources, context changes are much 
more frequent in TF resources. So there will be many redundant pipeline runs 
and can cause other issue. In my opinion, we can stick to ondemand rebalancer 
for these corner cases.
