I, and many pilots I know, interpret this rule to mean that flying
under part 91 on an IFR flight plan, it is illegal to use any portable
electronics not FAA-approved.

Sounds like you've changed your tune. Before, you were claiming the
regulation prohibited use of electronics when flying "hard IFR". Now you've
apparently figured out that only the flight rules under which the flight is
made matter, and that the meteorological conditions are irrelevant.

Glad you came around...
