Ok so if you need 72dp, couldn't you just add the difference in padding in the xml file? This way you keep Androids default Inset/Padding that they want us to use.
So: 72-16=56
Therefor: add 56dp padding to put yourself at an indent/margin total of 72dp.
Or you could just change the values in the Dimen.xml files. that's what I am doing now. It changes everything, the entire layout, including the ToolBar when implemented in the new proper Android way.
The link I added shows the Dimen values at 2dp because I changed it but it was default set at 16dp. Just FYI...
