Problem with experimental

I recently started to play because my girlfriend bought the game, and I loved it. And I was so excited for the copper golems experience. I actually couldn't stop talking about the cute golems with her. But. Weeks just passed sinced the last time I played. Because I noticed that being able to create copper golems prevents me of getting my beloved trophies. I'm so sad. I mean, there are add-ons with literally god-like weapons to defeat ender dragon and probably get the trophies, but having a pet to help me organize my items is a problem. I'm not mad, I'm just sad. I just wanted to play this amazing game, with my cute copper pet and my trophies but I can't. And I don't know if I wanna continuing my campaign since I just can't have everything the game has to offer at the cost of not having trophies. I don't know if you guys plan to make it non-experimental or letting us get trophies with experimental content. I'll probably play when this get fixed. AND I HOPE I DON'T HAVE TO START A NEW CAMPAIGN TO GET THE GOLEM AND THE TROPHIES. I'd really understand if it was a new biome, I'd have to create a new world. But the golem is and item/summon, and I think you have the power to give it an update the allows us to craft/summon mobs in our old worlds since it's not worldwide generated but just a spawn made by players. It's really boring that we have to create a new world and loose our progress everytime you add something to the game.
