In power query, the user will be able to mark a set of consequent steps, starting at the 1st one, and split the query so the marked steps become a new, independent query and the rest become a query referencing the 1st one as a source. This is useful when I found out that the first steps of a query are actually required for few other queries so I can create several referencing queries

This is already available in Power BI Desktop and Power Query. In the Query Editor dialog, you can go to the Applied Steps pane and right-click on a step, you will see a "Extract Previous" option which basically will split your query into two, having the second one reference the first "segment" as you propose.
