They could always add a "no destroy" keyring tab similar to the mount, illusion (and at some point familiar) keyring.
LOL I can see that announcement: Through sheer determination, hard work and ingenuity, Daybreak Games now proudly offers NO DESTROY key rings available in 1, 5, and 10 packs from the Marketplace. * Okay, we just copied the code from the Mount/Familiar key rings but still...OOH look, SHINY!
Well, yeah... it would look rather bad as a "feature". Nimbus keyring is the next feature one they should add. But the mechanic which is basically bag space hidden in the character sheet... is probably the easiest way to do it. PoD destroying stuff likely gets changed. PoD have a bad history of workarounds and misuse... they never get to sow discord to the "rules" for long.
Disagree. The next one they should to add is a bandolier keyring. So that you can put your weapons, shields, no damage items, etc in it and switch things around without them getting tossed about in your bags and unfindable.
Hidden corpses are also a problem because they are still picked up by Locate Corpse and Track Corpse. Be nice if they'd just fix that bug too, but yeah right when something's been buggy for years why fix it now. Dev logic.
