The request is to have the ability to place actions under a maintenance period in order to not have the action processed at all during the date/time..

The reason is that sometimes you would like to only like to disable the processing of an action during a particular date/time periods automatically rather than manually disabling / enabling the action.

Periodic change windows would be an example of where this would be applied or school holidays for an education related organisation.

The other benefit is that you could target individual triggers actions to be in maintenance rather than putting the host into maintenance where all the triggers would be disabled.
