One of my building blocks has reached end of life as we are no longer offering the service. I want to prevent new application teams from using this building block. Yet, I want to keep supporting existing users of this building block until they transition to a new service.

At the moment I can only flag a BBD as "use in Landing Zones only" which has the desired effect of hiding the BBD from the marketplace, but it's a bit confusing and feels like I'm using a workaround.

It would be more consistent with the way that Landing Zones and OSBs were offered on the marketplace if there was an explicit way to disable or "unpublished" a BBD.
