However. Suppose someone took this seriously and plugged in, say, a USB floppy drive (they exist[ed], I have one) in order to run themselves some genuinely old Wordstar or or Lotus 123 or Turbo Pascal from ancient disks they still have.

What about running a DOS based TCP/IP thing... would it see the ethernet port, or if absent, a USB ethernet dongle?
