Its not so much that it is considered too 'unsafe' these days (there is an element of that), its more that the willingness by the ADF to justify the workup and practice overheads for the more complex displays isn't there any more in such a resource constrained environment.
Plus the admin and planning overhead required at the unit level to mount the 'safety case' is a pretty big burden and has to be squeezed into an already busy 'operational' (doing the real job) tempo.
