I suggest some sort of refresher for divers who have been out of the water for any serious length of time (over say 1 year), but I can't see why doing such a refresher with an actual Instructor should be required. A good DM reviewing the basic skills and gear set up should be enough for most, unless there have been some major changes in gear since you last dived.
I was there myself, and I thought that an experienced diver ( like I saw myself at the time) could just jump back in, even after a few years out of the water. I was wrong. Gear had changed more significantly than I assumed, and I needed to adopt some new skills to use the "new" (at the time, at least for me) BCD. I got hurt, a bit, but mostly I scared myself.
Lesson learned.
Just a few minutes in the water with a DM or an Instructor, reviewing the newfangled equipment, in use, would have made my failure avoidable. We had discussed the new gear, but no one (including the dive op that supplied the rental) thought about an in water review. That was a long time ago now, and attitudes have changed, for the better I believe.
Today I do not mind hopping into the water at a resort or at a new dive op, to demonstrate simple mastery of skills. It costs little in down time for me, and everyone then better knows what to expect in the water.
