It has massive relevance. The civvies are rapidly moving away from radio based due to cost. That means rapidly reducing availabilory of VORDME and ILS. It just costs too much. Once CAT 3 autoland APV VNAV is the norm, forget using civvie bases as diversions. Issues with certification of systems as civilian certified RNP sensors is problematic. There is already airspace certified as RNAV only through Europe and the Middle East. No certification (to civilian equivalent standard)? No play. And as it was introduced for capacity reasons, forget an exemption during busy periods.
Certainly be interesting to see how we will cope with only three major radio nav aids in the UK as well. There are other cns atm issues on top of PBN.
So can't do anything until probably d day -6 months, then there will be panic as we try to meet the equipment, operational and training requirements, a la 8.33 spacing.
Also, fms based 4D nav requirements are inbound in the next few years.
