A mod (Addon for Thaumcraft) that allows items to be sould bound - for preserving them past death.
Between the preserve items in inventory on death gamerule and gravestone mods, a lot of risk is taken out of the game. However, loosing items to the void / the 5 minute rule because you couldn't find them in time, fire/lava or explosion is just lame.
So as a compromise, soul bound items would still be "dropped" normally on player death. And need to be picked up by the player.
Items protected with this enchantment would however:
1. not be destroyed by environmental factors such as fire, lava, explosions (including creeper and wither) or falling out the world.
2. not be destroyed by timing out.
3. would not fall very far / be carried off by water.
4. other players. Or NPCs such as zombies. would not be able to pick them up.
This preserves the basic mechanic of having to go and get your stuff. from a potentially dangerous place. But preserves them from the very volatile and hard to plan for reasons they might not be there when you finally get to them. But also means that inventory items NOT protected, are completely vulnerable as normal.
what if there was perhaps another way of doing this.
there could be a potion that you could either brew yourself in a brewing stand, or it could be a trade with villagers.
when you drink this potion you'll leave something behind when you die, perhaps an urn or something similar.
this urn will hold both your items and experience upon death, and you can reclaim this earn at the location where you've died.
there's still the problem that if you break the urn your belongings will go flying around like crazy, or it takes time to break it.
so instead of having to break the urn, how about you have to right click the urn to reclaim your items and experience?
but another problem comes up, what if your inventory was completely full when you died, but you now have other items in your inventory aswell when you try to reclaim your belongings, those items need to go somewhere aswell.
so what if you've new items in your inventory and right click the urn, your items get switched. so your belongings are taken out of the urn and put back in your inventory (armor and baubles would go in the correct slot aswell) and your other items get transferred into the urn. now to prevent people from abusing this as an easy way to switch inventories this could only be done once, and afterwards you'll need to either shift-right click the urn and pick it up, or break the urn to reclaim your items. you'll also be able to shift-right click the urn immediatly instead of switching inventories first, so if you want you're able to take the urn somewhere else and safely reclaim your belongings
but things could still go wrong, such as a creeper blowing up the urn or another player breaking it. because of this the urn will have a blast resistance of obsidian, and the first 5 minutes after it spawned another player is not able to break it, this way players can't grief other players by having a bunch of urns spawn in or near their base which they can't break, but other players can't easily steal urns either.
do note that the potion should be a one-time use only, if you die and an urn spawns, you'll need to drink another potion if you want to have another urn spawn, and the effect shouldn't stack, so you wouldn't be able to drink like a dozen of these potions and never have to drink one again
but there's 1 more problem you may have, it may happen that you died in a very hard to reach place, or miles and miles away from your base, so there could also be a ritual you could do that'll cause the urn to teleport to your position. I know I've been in these situations before and died a few dozen more times before I was finally able to reclaim my items. this ritual needs to be done within the first 5 minutes after the urn spawns, and it'll act similar to enderchests, another urn is created which is linked to the urn that spawned when you died. this new urn will do exactly the same as the other urn, but it'll disappear after 5 minutes, and with that the other urn will also disappear, so if you do this ritual you'll need to be sure that you can complete this ritual properly otherwise you'll still lose your belongings
