@johndiver999's post describes my recent West Palm Beach triple wreck dive off of Dustin's Florida Scuba Charter's boat almost to a T.
Fast hot drop into moderate current in medium visibility conditions, negative entry if possible, free descent to the bottom at 90' which isn't visible for most of the descent. Divers end up all over the place as expected- I dive solo and didn't see anyone else swimming close together. Dustin didn't request anyone shoot a bag though. Just surface after the last wreck or sooner if necessary - taking the usual precautions to listen and do the 360 upon surfacing to make sure you aren't run down and then inflate your SMB. It's a heck of a lot easier and enjoyable to dive this way- not having to make your way back to a fixed point, ascend whenever and wherever you want and you'll be picked up by the boat. It's really not difficult for confident divers with at least AOW training which is the required minimum certification level for this sort of diving.
Also as per
@johndiver999 post a few bad divers can make things difficult for the Captain but in a dive as described above, all they have to do is surface- anywhere anytime and they'll be picked up and won't be an issue for anyone else. Assuming they don't panic and ascend to quickly or whatever. On one of the dives that day someone forgot their weights, he turned around, picked them up immediately, they got squared away, he redid the approach to the first wreck and in they went, no issue.
On the boat that day were divers doing wrecks and other divers hunting for lobsters on reefs. Dustin was able to accommodate all of us. Nobody got lost or run over. And we all got home safely.
Dive Ops need to be flexible and accommodate the full range of diving skills or they might find they aren't filling up their boats.
