Remove minimum frequency of outgoing messages

For certain uses cases having a minimum of 1 minute cool down for outgoing messages to a given user is a deal breaker. If we understand the risks of overwhelming the user with messages does it make sense to provide the option to remove the frequency limitations? In my particular use case I want to scale internal communications based on related business events associated with a users client portfolio. This may result in many similar messages being sent on behalf of a different client/customer. Batching would be fine if I didn’t also have the use case to isolate the messages by client/customer as well.
