This one I really found excessive. There's pretty a 1:1 relationship
between the steps and the stamp files, so anything that has knowledge
of the internal steps of a package can also know about the stamp files.

As it's more controversial than the rest of the series, I left it
aside. I'll for now mark it as Rejected, but I'm also ready to revisit
that if need be.
