Is your feature request related to a problem? Please describe.
When running different servers, I really wish I had config options to choose what kinds of items to keep on death, which to drop into the grave, and which to lose permanently.

Describe the solution you'd like
Would love to see config options like:
EquippedOnDeath= keep/grave/destroy (especially if compatible with curios!)
ExpOnDeath = keep/graveAll/graveVanilla/destroy (options for whether the grave returns all your exp, or just the vanilla amount)
HotbarOnDeath = keep/grave/destroy
InventoryMainOnDeath = keep/grave/destroy

Describe alternatives you've considered
I looked into what other kinds of mods may handle this, such as GameRule-tweaking mods or other grave mods, but haven't seen anything like this (for forge). Alternatively, a possible blacklist/whitelist for items kept on you or stored in the grave?

Additional context
Cosmetic Armor Reworked is the only forge mod I've found that individually lets me specify to keep that inv on death. T_T Not sure if that would be a useful reference at all. https://www.curseforge.com/minecraft/mc-mods/cosmetic-armor-reworked

Would also like to see this. The only alternative is Corpse Complex and its been stuck on 1.16.5 for a while now. To add on, perhaps a configurable chance for each inventory slot to drop on death? Eg. 40% chance for each item in your inventory to drop, 30% chance for a piece of your armor to drop, etc.

Wish this would be done more, as it's really easy for powerful enemies to spawn camp your grave.

ExpOnDeath = keep/graveAll/graveVanilla/destroy

I would also like to see here the percent option for the amount of stored experience in the grave, and next to it the option to set this percentage.
So that, for example, it could be set to save 75% of the experience at the time of death.
