I am inclined to go with this option as well. When chaining parts with 
the `after` keyword, what usually comes """before""" are your 
dependencies whereas when creating a snap one would work on the leaves 
(the parts holding the most `after`s). I think of it almost as a 
`Build-Depends` in `debian/control`
