I use Rotella T4 Diesel Oil in every vehicle I own, including my lawn mower, I have done so for as long as I can remember. There are people I know who are adamant that it can not be used in vehicles that have a dry clutch

.
No
No, Shell Rotella T4 and T6 cannot be used in vehicles with a dry clutch. These oils are specifically designed for wet clutch applications and do not contain friction modifiers, which are necessary for dry clutches. Using these oils in a vehicle with a dry clutch can lead to clutch slippage and other performance issues. It is recommended to use motorcycle-specific oils that meet the JASO MA1/2 standards for wet clutch compatibility.

What I want to know is why not ? that make no sense to me whatsoever.  What am I missing ?

I think they are missing the part where the clutch is outside the crankcase.  Plus, anything 40 weight is already well on the way to motorcycle oil in the first place.  On ADV, there would already be a meme posted saying “Not this crap again”.

Not that you need my permission, but you’re doing just fine with the program you are already running.
