It is necessary to ensure the license plate does not behave like a conductor across the top contacts of the ribbon cable shown below:
From The Factory
In the short term, we will be shipping product with the fiberglass tape as shown. We will also be sending tape for customers to place along the top edge of the license plate:

Additional Short Term Measures
While this might not be completely necessary, it certainly eliminates any chance of contact with the ribbon connections. One of our backers actually notched out the plate as shown:
