I sent it to Frikkle on the discord and he said he'll send it to Niller and other mods !
This is so that it doesnt get out easily

And I forwarded the information to Niller.

Thanks for letting us know. I've known about this issue for quite some time, but have decided not to do anything, as it would require disabling items that are fairly frequently used. If people really want to dupe things, I think they'll always find a way.

Closing this issue as "won't fix because of reasons".
