You might think it's logical, but it's misleading, because it leads people to believe that the -D designation tells you something about AF

No, because it wasn't meant as an explanation of all those abbreviations for new users of the system, but as a (fairly typical) abbreviation used by those already familiar with the system.

The list is also incomplete. If we wanted such a list, to incorporate both the type of AF and the type of diaphragm control, it might look like this:

  • AF
  • AF D
  • AF G
  • AF-I D
  • AF-S D
  • AF-S G
  • AF-S E
  • AF-P G
  • AF-P E

Well, ok, it doesn't make things any less complicated...

The way Nikon have structured their lens naming system means that this subject is always going to be complicated.  Sadly, attempts to simplify it (even when well-intentioned) tend to create confusion.

...but still: even on that list, an 'AF D' lens is a screw-driven lens

Yes - but so are AF and AF G lenses.
