Except that the 'work around' does maintain security since it preserves the original FaceID chip assembly.

"The most sophisticated repair shops have found a workaround, but it’s not a quick, clever hack—it’s physically moving a soldered chip from the original screen onto the replacement. "

I'm not convinced by this - if you look at an iPhone 13's screen, it's entirely separate from the face ID hardware. https://i.imgur.com/D63HrIT.png (screenshot from [0])

On iPhones X through 12, if you kept the Face ID hardware and only changed the display, Face ID would continue to work. On the iPhone 13 series, if you keep the Face ID hardware and change the display, Face ID stops working.

The chip which people are removing seems to serve only to identify the display - nothing to do with the Face ID system. Apple has been using this chip for years to disable "true tone" display functionality when the screen was swapped (unless it was programmed by a proprietary tool, only available to first-party repair shops) - they're now also tying it disable Face ID.
