My idea for adding new weapons to the game

I’ve never seen this but this might’ve been done in other games before so please correct me if I’m wrong. I think that when Embark is ready to add a new gun to the game, instead of simply making a trailer or a post and releasing it, add it in without telling us. Just throw it into the loot pool and make it extra rare. Make the gun feel like a myth, something no one’s sure is real. This makes additions more organic and creates mystery. This can even give embark a way to test new guns out without fully releasing them. There might be some problems with this that I’m not thinking about but I’d love to hear thoughts.
