Github user kunal642 commented on the issue:
    @jackylk We have an Event architecture which can be used to perform pre and post actions.
I think it is better to add the validations in pre listeners.
    Another point is that if we add validation in a strategy like in #1447 then we would have
to look up the carbon table twice(once for validation and other in the actual flow) which
would decrease the performance. In listener interface, we can be shared the carbon table among
various listeners.
