For things like stack-list, the default would be to display a masked value like we do for parameters. I think we should then add the ability to retrieve the unmasked values for parameters and outputs.

I think it could work for dashboards as well. The behavior would be to display the masked value and add a control that once activated, retrieves the unmasked value. Since one hopes this dashboard would be using some library like python-heatclient, its not that much work.

As to there being no security value in masking sensitive data, we already have a precedent for this in parameters without having the ability to get the unmasked values IIRC. The fact that those are user-supplied sensitive data versus system generated sensitive data is irrelevant since its the template author (which isn't always the person deploying the template) that determines a value's sensitivity, not some inherent property of the value.
