Greetings, @Ivan_ !
We do not have a final decision for this suggestion just yet, but we would like to provide some preliminary information. A lot of these items are restricted to only cast in PvP areas, which means they do nothing when cast on the world. Some of the items are very very old, so we might not be able to update them anymore, as we tend not to update super old items.
Feel free to provide a list if you want us to look further into other items, but it is likely that they too will be PvP restricted.
Once we have a final decision, we will let you know. I hope you have a magical day!
The items I showcased in the orignal screenshot are all still "castable" in the main world/housing, which is my main concern - I dont want to lose those items by them accidentally going off (which is exactly what happened with the magical clock, that inspired me to make the thread in first place).
Maybe its best to categorize the items and go from there
1. Old potions - Some of the old event potions immediately disappear when consumed (Valentine 2016 and Halloween 2016 ones for example), and the old "world" potions are still throwable (even tho they dont do anything anymore, for example I tested with Amortentia potions)
*extremely old potions take time to be drinked, which is fine (they usually have white font names)
2. Old food items - same thing as above, theres consumable food that immediately disappears, food items with "uses" (provided in the screenshot), as well as "vanilla" minecraft food you can slowly eat away, its totally unrelated to PVP zones. If only the items I provided in the screenshot were updated to not have "uses" anymore and just exist as items, I think it would already help a lot
3. Old magical items like the ones I showed in the screenshot, which still "cast" in the main world/housing
