I understand your position. Perhaps you could simply clarify what you mean by "dullest tool in the shed".
Perhaps what we should do here is have some proponents of "one handing when necessary" post some photos or videos of that said saw use in action. This could be commented on by the opponents of the practice.

"dullest tool in the shed"...least intelligent, poorest learner, least capable, most belligerant, most likely to not observe safety....come on man...
Anyhoo pal, here is whatcha lookin for. Have at it, as I know you will, but you are not likely qualified to carry my jock when it comes to making bucks, length of safety record, wealthy high level clients, etc. etc.....just keep that in mind.
This is life in the real tree world for most of the arbs that just have a 2 man crew for decades and decades...cutting and holding and tossing, holding the tip of a log so it doesn't hold wood and swing backwards into the roof, etc., headlocking and one handing...etc etc.
My brain knows exactly just how much my hand and arm can handle by thousands and thousands or reps over the years.
Here is a decent size century old sug. maple with verticillium wilt. It is still a viable tree on the late 1800's property (my wife grew up in this house) even after being cut back. One handing going on because I am and almost always have been just a 2 man crew. Don't feel sorry for me because I live in a 400k house, have mass equipment and toys and have made millions over the years with just me and a gm.
The cut backs are obviously over the wires but it could just as well be over a slate roof or a high value landscape etc. Lots and lots of cuts. Not going to attach a rope to every one and 2 hand cut...duh. Not going to say I do either just to be part of the pack on the Buzz.
Also...and please take NOTE of this...not going to EVER let my climber do this and not recommending this to anyone. As I have said before...I am not trying to teach anyone anything on forums. I just like to yak it up with peers.
My, in the miniscule amount of time over 40 plus years I have used one, climber is not going to one hand because safety standards prohibit this and if he were injured then I would be completely liable. I understand this fully and cover my as s.
I am not breaking ANY laws, ordinances, standards, religions or rules of any type in this vid. I am the company owner for 4 decades and not subject to "dullest man" regs. as I am not an employee.
You can see in these typical cuts (vid taken a couple or three years ago) that at NO time is my hand or arm or body (in bucket) in any jeopardy of being cut. The plane of the bar is being intentionally located so that kick back can't hit me, my hand and arm and shoulder...all out of range of kick back or any other scenario. Kick back will travel in the plane of the bar.
You want to have enough hand and wrist strength to do this all day and then some when storms hit. My regimen is to torque a long handled sledge hammer around in all direction every couple of days and wrist curls and hand grip exercises.
No bucket lanyard on but that, along with hard hat use has changed in the last couple of years. I now use them both.
I read in TCI accidents where a guy got a bucket stuck under a limb and did not know it and when it released he was shot out like a pea from a plastic spoon and that did it for me. The hard hat just because I have made my gm wear one so I wear one to be fair. If my gm was injured without a brain bucket on, again, I would be completely liable.
