Which Tim explained is the best example too....
We need to discuss on how to avoid these kinds of insertions from back-end.
#1, What are the alternate approaches to overcome this problem?
#2, One more case is one would have a generic report, however in one of the use case certain values needs to be bolded. In that case, front-end will not know about this. It would be complex in the front-end side to deal with it. Forwarding several variables from back-end for special treatment would be messy.
