Super-forced building is amazin feature, but there should be also oprion to remove everything but what you past in the area af bluepring.

Most common use case placing belt balancer over existing belt Lead to unintended topology

I second this.

I see a need for this as well.

I want to suggest it in the form of:
Allow deconstruction orders within blueprints.

2.1 Experimental Bump

The simplest way to implement this that I can see would be a special 1x1 building which has the special property that any ghost of it is automatically deleted. You can still create them and place them manually (though they'd probably be hidden and only available in editor mode, like infinity pipes and loaders), and thus you can blueprint them, and thus if you super-force-build a blueprint that contains them, any objects on that tile they would occupy are automatically marked for deconstruction, but since the ghost of the special building itself is then automatically deleted, nothing will actually be built in that space.

That said, a more complicated and feature-rich system would be nice. For instance, I often wish there were a way to have my blueprints remove any rail signals present in certain locations because I know those signals will become invalid after the new rail is placed; however I do not want to delete anything other than rail signals which might happen to be there.
