Now forgive me for my lack of mechanical knowledge here, but I think I'm right in saying that the major difference between an off-road/enduro bike and a 4x4 car is the number of wheels.
If you get yourself into difficulties that would usually result in a stall in a car, the chances are that it is still relatively upright (or, hopefully, not on its roof anyway) and all the oil, petrol, tin cans in the back, etc., tend to stay in the right place, whether or not the engine is running.
If you get yourself into the same position on a bike and fail to control the situation to the point that you fall off - and you have fitted some gizmo that keeps the engine running while the bike is on its side/upside down, the likelihood is that you are going to pump oil or fuel where it shouldn't go and thus risk damaging the engine.
Here's what happened to Roynie's Tiger 955i when it kept running after an upset. (Oil went through the air box into the top of the cylinders, which put too much pressure on the con-rod, which then broke and punched a dinky little hole in the engine case.)
Respectfully suggest OP learns better clutch control.
