We do as per the FCTM now. Previously we did as you. To be honest I don't see the point into force tuning nav aids just 'to have something to point at' when it takes seconds to insert if required for holding or whatever. Obviously doesn't apply if you are doing a VOR or NDB selected or managed.
Secondly if you were to have a dual FMGC failure and NEED a navaid for general Nav you would have to go to backup nav anyway and dial it in, so all in all... what is the point.
