Hi Adam, sorry I missed this part:

> What are the benefits of a Deeper History?

Same benefits as the current history - it would allow you to tweak construction curves to make modifications to your model.

This currently works in MoI for cases where all the input objects are in your model - for example if you do a revolve you can then edit the original input curve and the revolve will update.

Right now it is pretty easy to have the history chain get broken though, a deeper history would just enable the same kind of edits but without being broken when operations such as booleans or fillets are applied.
