When comparing this to spawners just understand spawners are mainly movable and in the game to reduce lag, having spawners reduces the need for elaborate mob farms that tend to lag the server so the ability to move them is more to keep the lack of mob farms.

In default vanilla minecraft budding amethyst only spawns in set locations in the world sometimes in an non ideal layout and in very inconvenient places, however spawners this also is the case for, i do think nbt text added to the budding saying this cannot be moved once placed could def help if possible, im on the fence tho abt moving this specific item but a warning before placing it like heads could also help if they intend on keeping it this way i could see the dev team going either way making it pickup possible or not so im curious to the direction that is taken with it i see the challenges that come with not moving them and also how it makes the item not able to be traded once placed which can add more depth to if you want to originally place or sell it also warning on the item will show you should plan where its home will be first once u do goto place it
