Yes I believe the visual approach ban in Italy is because of the accident in Cagliari a while back.
Ok, if they crashed on an ILS would the have banned ILS approaches. This is scurvy thinking at the highest (lowest) level. Basic flying is visual approaches; they shouldn't require much briefing beyond the crew confirming the airport/traffic is in sight and the right one, everything else was in the IFR approach brief. I might say, "plan a 2 mile final" as I entered the pattern so the other pilot will be ready to speak if I go sailing past a 2 mile final.
TW. About a minimum of 3 Mike spacing, maybe 5, I arrange so the traffic ahead is clear by the time you hit 3/4 of mile on final.
