One problem is commercial. I know of one airline who used to allow visual approaches in the hope of saving time & fuel. They did this in their 'old' a/c. Now with shiny new wizz-bang a/c and all that great SA information you'd expect it to be even easier. Rapid expansion has led to a vast spectrum of abilities and experience. Philosophy now dissuades from short cut visuals. One of the reasons was the large increase in G.A's as soon as CAVOK hit the airfields. Guys thinking they could thread the needle again after months of IFR stuff. The 'lack of fuel & time saving' by such antics caused a shift in attitude and rather than address the root cause = lack of training & practice, the solution was to restrict it. To counter this attitude by the CAA's there will be a great bun-fight and my guess is the airlines would win it.
