Back in the day, carabiners did not usually have locking gates, or the locks were not spring-loaded. Link two such carabiners together, give them just the right twist, and they will separate as if by magic, without touching either gate by hand.
Now, I think it's more a matter of micro-point loading, where straps would spread the forces applied, more evenly. Point loading maybe could cause a metal fracture, but it''s all theory, to me. I do not know if a modern (5kg+) steel carabiner has ever failed due to linking to a second carabiner, but it's still one less thing to go wrong, if you use only one carabiner. As general advice, I like to share this: "Beware of jury-rigs, on any flying gear. Get it right, or don't go." We do this flying stuff for FUN!
So one time, 'way back in the day, a new pilot was telling me that two linked carabiners could not simply separate, like I had tried to tell him. So, I just kept clicking two carabiners together, giving them the little twist, and having them fall apart. I did this repeatedly, as he kept talking, until he finally ran out of words and yelled at me "Will you STOP
doing that!" We had a good laugh together, but he got the message.
Pssst! New pilot? Free advice, maybe worth the price,
