Not sure how that matters. Part 23 never applied to E-AB or E-LSA certificated aircraft. For us standard OPLIMs and 91.205 are the governing directives. 91.205’s wording changed to magnetic direction indicator years ago to address the proliferation of magnetometers. So in our world a whisky compass or a magnetometer meets the 91.205 requirement— which one you choose to use is up to you.

I'd say it matters for the reason RV7A Flyer stated above - this is a "discussion" that many RV-ers have to have with their DAR - perhaps this change will help sunset that argument. We can hope.
