I would not do this change. I imagine that we should find a much clever way of notifying user. Avi suggested to me that we could have exception that would be caught and letting the used decide if he wants to put a UI or not for headless image for examples.
This is already how ComplexProgressIndicator works. Your underlying code raises ProgressNotifications.
So what we'd need is two things - A. A list of all places that such sometimes-interactive processes call the UI (in order to convert them to raising exceptions) B. A few other handlers of such exceptions, where Morphic is not present (versions for MVC and for the emergency evaluator prompt might be a good start).

The most obvious candidates are: - Object>>inform: - Object>>confirm: - Object>>confirm:orCancel: - Object>>confirm:trueChoice:falseChoice: - String>>displayProgressAt:from:to:during: - the class side protocol of FillInTheBlank
Some users of PopUpMenu and SelectionMenu may also need to be modified.
If nobody's tackled this cleanup by early next week, I volunteer to start it then.

Hi avi
Please do, I will review it. I think that this kind of changes will really improve the core.
We have enough to do with SystemDictionary and the core behavior.
