Is this likely to be a breaking change?

No

What are you requesting?

Currently, Structure and Feature have boolean place(ServerWorld, Vector3i), which does not allow a mod like WorldEdit to capture or modify the changes. It would be nice if we could get a callback for each block/entity so that WorldEdit may place it, rather than placing it directly into the world. This allows undo, masking, and better control of block placement than using Minecraft's code directly.
