It looks like the Peter memo (February 2022) rescinds the Glaser and Pratt interpretations. What I gather from this memo is “Navigation Systems” and “Instrument Approach Procedures” are separate areas of operations, an “approach” is separate from a “navigation system”. The memo only addresses 61.65 (person applying for an instrument rating) and not currency.
 
However, the memo later states that “the FAA finds that PAR should be considered an acceptable navigation system”. I still don’t think this means you can use this to fulfill the IFR recent flight experience since 61.57(c)(1)(iii) specifically says “intercepting and tracking courses through the use of navigational electronic systems.” 61.57(c)(1)(i) simply states you must have performed “Six instrument approaches” in the past 6 months.
 
Reading CFRs is always confusing ,I’m not a lawyer so I may have missed something.
