E base A065 means IFRs that happily operate OCTA now at A080 & A070 in the best G that exists in the world (no other has DTI in G) are now going to be forced to lower levels and mixing it with tons more other airspace users.
if you can track point A to point B direct without clearance and are happy with the DTI service why would you want a clearance with 10 waypoints and turns between A & B and the chance of having yr level changed or heading changed for separation/delaying action ? Makes no sense.
This makes lower level airspace much more dangerous I think ?
