I would like to see you single hand set and douse all 4,000 sq ft of our kite without a sock. Racing we don't need socks, we use a crew of 18. Socks may be a complication but for short handed sail handling they really are a necessity.
I don't think it is all that binary. There are a lot things which make sense on bigger boats, but which I see as unnecessary complexities or even bad ideas on smaller boats. In my mind, things like wheel steering, electric winches, in-mast furlers, and windlasses fall in that category where they make sense for bigger boats and are bad ideas on smaller boats.
When it comes to spinnaker socks, I routinely fly my spinnaker single-handed without a sock on my 38 footer, and have carried and doused it in 15 knots apparent (over 20 knots true) single-handed without a problem. But I doubt that I could do that on a boat that is more than 3-4 feet bigger than mine, or on a masthead rig.
As Dave (SVAuspicious) noted our opinions are rarely this far apart, and when we have held differing opinions, I have usually ended up thinking that Dave's position has usually been basically more safety conscious and a better idea for most folks. *grin*
In this case, I have had such bad experiences with both spinnaker socks and with assyms. that I have a tough time considering them to be the safer option on a boat that is small enough to be single-handed without a sock.
But that does not mean that I think that Dave is wrong. His chutes are much larger than mine, and he may have procedures for handling the sail in the sock which prevents them from going up with a wrap.
And the one thing that I will say in favor of a sock, is that unless there is a bad wrap on the forestay, if the sock fails, in an emergency you can always do the kind of drop that you would with without a sock and clean up the mess later.
