Usefullness of Stacking Ghosts and Entities Marked for Deconstruction

[DreamConspiracy]

Since at least version 0.16, you can place a ghost of an entity, and a real entity marked for deconstruction on top of each other. This does not seem very useful to me, so I was going to suggest a different behavior. However, before I do so: What are the valid use cases of this, and why might we want to keep it?

Otherwise the entity would be blocking a ghost placement, or blueprint placement. Marked for deconstruction entities are deactivated, and are practically just waiting for a construction robot to come collect them. Once you mark something for decon, that space is instantly "free" for BP ghost planning.
