This issue can be closed. Mojang probably doesn't have any intention to bring this command back into the game, and /transfer exists with Bedrock Dedicated Server
Mojang Studios is already aware of this issue, so I would consider this issue invalid. Because I am not an employee I cannot close this issue.
No. A 3-year-old pure survival realm. Has been an issue since we upgraded to 1.19.50
Sorry about that, I've edited my original post.
