The "Managed Properties" flags on solution components are a great way of preventing customizers in downstream environments or ISV customer environments from making customizations on top of what you are delivering in your managed solution.

These flags are however by default set to "Customizable", meaning there is no lock.
These flags must be set manually, component by component.

In an ISV scenario, or even when you have core functionality that "shouldn't be messed with" in a custom implementation, it would be great to be able to specify on solution level that everything in this solution should be flagged as "Not customizable".

We could always create another XrmToolBox tool looping through all components and setting/clearing that flag - but this would still not give the proper solution level indication of the customizable properties of the solution.
