Again, not a single official I've ever spoken to (on or off the board) aside from you believes this doesn't say you need to do a DF on this play.

I can only imagine it applying in your #2, and no, I can't imagine that they wrote a case play specifically for that purpose. But it is equally difficult for me to imagine that a case play was written to specify that one team should be penalized if the officials improperly use preliminary foul signals, and that this is true even though the case play in question does not actually mention preliminary foul signals.
