There is a fictional example why you might need underwater gear removal skills going viral in China last year: in a movie there is a scene where a female was lured to a submerged cage and her boyfriend closed the cage door behind her, and being unable to remove her backmount gear (which is jacket BC in the scene btw) and squeeze through the spacing between iron bars she died in a cinematic desperation. This has been used by many rec-level instructors on Chinese social media to tell their students how important the "kit removal" skill is.
After this example went viral I even heard at least two separate people (one of which is an active non-DIR instructor) stating that the selling of DIR/Horgarthian gears to rec-level divers is dangerous - and one argument they used was that you could not easily remove and replace your rig underwater, especially if you also used long hose and a short hose with necklace. Other reasons included the lack of buckles on shoulder strap which made it hard for people to remove rigs from an unconscious diver (funnily, the reason why DIR/Horgarthian gears do not have these buckles is also safety).
But nonetheless I do not think this example has a lot of real-world implications as in order to make it happen, you have to have a buddy with a very malicious intent towards you, stick your head to a very confined space with such buddy on your tail, and finally, be too lazy to try even once removing your rig underwater (in a very confined environment which reduces the difficulty) even knowing the consequence is your death.
