Alderney has an LPV approach -- the glideslope is based on GNSS with SBAS, not Baro. There are lots more (including Aldergrove and LHR) with LNAV/VNAV lines (with the intention that these are BaroVNAV).
The only references to RNP phraseology I can find are along the lines of "to be promulgated".
I image that the existing phraseology "R-Nav approach Runway XX" will persist, despite the specification technically being RNP APCH.
