Textbox use auto-size to automate border placement
Under "text frame options" we have "auto-size" which is an amazing feature, but not used to its full potential.
If we combine this with textbox borders, I could automate text boxes with Data Merge on a grand scale.
Most of the groundwork for this feature already exists. All that's left is to be able to set a rectangle to automatically resize to match a textbox.
