I can only speak to FAA policy. The final segment of a VOR approach must use VOR raw data. In terminal sensitivity LNAV is not VOR raw data.
Having said that, if any given commercial operator can get ops specs approval to use LNAV in terminal mode (RNP 1.0) in lieu of VOR raw data, then an exception has been granted, right or wrong.
We all know that LNAV in the terminal mode will likely do a better job of flying the final approach segment than tracking raw VOR, but the integrity and alerting will be lacking. And, that will probably never matter.
How many VOR approaches are flown these days anyway?
