There should be a way to have a dialog box appear in the workspace to notify the user about the output of the transformer. There is the logger transformer, but the message supplied only appears in the translation log. It would be helpful if you could run the workflow and get feedback that could then lead to alternative workflows depending on the output

While not generally considered best practice, and must not be used for FME Server, you could use the ctypes.windll library in a python caller
import ctypes def processFeature(feature): msg = "This is the message that appears" title = "This is the title of the message box" x = ctypes.windll.user32.MessageBoxA(0, msg, title, 1) feature.setAttribute("Response",x)In this example, pressing the okay button returns a value of 1, and cancel a value of 2. There are several different message box available via windows, and quite a few settings for them.
You could look into https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-messagebox is you want more details.
