"Second, the D-ring INSIDE the pouch is to clip things off that are INSIDE. You unclip BEFORE you remove the item from the pouch. Yes, metal-to-metal connections are to be avoided, but if something is INSIDE the pouch it can't hang up on anything - so the argument against metal-to-metal doesn't apply (unless you're making it just to be a purist!)
Second, metal-to-metal isn't forbidden PROVIDED there is a severable link somewhere in the chain. For example, when you clip your primary off its a metal-to-metal link. You put in a "fusable link" - an O-ring or cave line - so that if you need to get it off and the snap freezes you can - with some effort."
I understand the purist aspect, and your wish to keep religion private, but if you are looking at the different aspects then you need to have all the info.
The gear is most effectively removed by just dumping it all out and unclipping. Something like a spool could get jammed and one could not remove it all all. The reason for metal to metal avoidance is not just because of entanglment, but also due to not being able to use the piece of equipment that gets hung up if the bolt snap jams due to sand, salt, etc.
