What's wrong with a little progress? I think it's good. Sustainable progress though is the way to go, just as long as we don't gold plate everything.
Personally, I don't think airlines or pilots have a problem with the approaches at Hobart. You're either going to fly an ILS RWY 12 or a VOR/RNAV RWY 30 in bad weather or a DME/GPS arrival for a visual circuit under ATC guidance. It's not that difficult for jets to fly and the risks are relatively low. Perhaps different for other aircraft.
Re classes of airspace and risk levels, there's bigger fish to fry.
