update the XP loss system

I saw the updates coming to minecraft up close from 7 years and the things cooming are changes to make the game more casual and the game feels less punishing and more confortable to play, but something that always see and still feel unfair is the loss of the XP, if you go with high levels of xp and you die always you get 7 levels but not more, something for casual and progressive gameplay make this boring and unfair, make progress of hours feels in vain, for someone who die for anoyhing sometimes is tedious and drop the gameplay.
something more interesting is loss of XP for percentage, like something 70/30, 70% of loss and 30% of recoverable where you died, something like that will feel less anoying, if that come with a problem for players who reach high levels up to 100 the percentage for the xp recoverable will be less, like exponentialy will be less the recoverable XP
