Transform Quest Items Into Untradable/normal Ones After Finishing The Quest

we all know how much we hate quest items, and how much space they take because we can't get rid of them
(excepting the only 2 possible ways)

there is one way to fix it which took me long to discover

do you guys know when they ask you for X items in a quest? well, in the last step, they could get rid of your quest item and make it untradable (after you finished all the quests that item is needed in)
Example:
When you are doing [Creeper Infiltration] you will have to get a Creeper Mask, which is a quest item, and after finishing the ToL quest, it becomes practically useless, so... in the last step of the ToL's quest, they could get rid of this mask making it untradable or normal

i believe this is the only way to fix the quest items space problem without having to use any bug (if the daily reward chest one is a bug)

 

This could work, so long as the items stay quest items while they're still needed for future quests.

 

And when the developers don't want to make new quests that require those items,in the last quest with that item these will dissapear

 

Well we can't really change items already out there into untradeable, and most quest items are used for future quests anyway. The ones that aren't will be taken care of in the future.

f - hey dude i got a quest item what is it for
m - a level 75 or something quest lol
f - *throws it away*

 

i said the example with ToL and creeper infil
after doing ToL, you will not need the creeper mask anymore so you could throw it away after finishing ToL
another example would be how quest untradable items like Maro's Jewel Eye or Baab's wool dissappears from the inv when the quest asks you them
they could do the same with quest items, passing them to untradable when the last quest where you use it finishes
