This RNP AR IAP just became effective this past Thursday. Note the vast improvement in both safety and minimums over the other RNAV IAP aligned with Runway 24.
Where possible an RNP AR approach is supposed to have a line of minimums of RNP 0.30 with a non-RNP missed approach. Then, if necessary other lines of lower minimums using smaller RNP values. Because of the close-in terrain issues at this runway end, only RNP 0.10 would fit.
As good as these concepts are, I believe the equipment bar is set far higher than necessary. The standards were established on airline equippage when the standards were implemented and fail to take into account other methods of compliance; particulary SBAS.
