You're forgetting something else: Boot Camp Assistant, the application in the Utilities folder on Macs.
For those who don't know, the Boot Camp Assistant is a Mac OS X application that walks you through starting a Windows installation. It asks you to insert a CD-R or USB drive to copy Windows drivers. It partitions your HD/SSD for you. It asks for you to insert your Windows media, verifies it, sets the system hardware to boot from it, then restarts the hardware.
Later versions of Boot Camp Assistant automatically slipstream the Apple drivers installation into the Windows installer USB drive (using the configuration file interfaces Microsoft provides for OEMs to run their own custom installers at installation time).
I wouldn't say that it's accurate that "the story should be that Bootcamp has been removed from these Macintosh systems," because the Boot Camp Assistant still exists on these systems, and Apple supports the installation of Windows on their hardware when using this application.
