Maybe 10 years ago, but we have have WAAS now and soon more airports will have LAAS.  I fly out of the Northeast and airports like Tetrrboro in NJ removed all their VOR approaches.  Many fully IFR capable aircraft don't even have a DME receiver and use a TSO certified GPS to provide DME. People aren't going to use VOR approaches as a backup since, like NDB's, they won't exist anymore.
