Vitara LY in the snow and a question about driving mode LOCK

Hello colleagues, today I have done the first extensive ride in the snow with the little one (with deep snow and other not so easy moments). I don’t want to give too much room to my honest enthusiasm; absolute class, stable, easy to master, smooth working of the all-wheel system etc., everything in the mode SNOW, LOCK I took only for interest, not needed (which I never thought about in view of the conditions). Nevertheless, my question refers to LOCK: I am interested in Is there any technical information or background/experience why this mode should not be used in the long term or (why) this is technically harmful? In the back of my mind I have such a pale memory, but I don’t even know if it was Suzuki. Thanks and greeting prio PS: the search I did not try to find
