Oh, I see. I'm fine with that.

Though to further the discussion, maybe we want to check if such a variable
is set and if so actually show the deletion? I have the impression that most
of the variables are not set, and yet we unconditionally delete them, "just to
be sure". Maybe we'd only want to delete them if we actually have them
set in the superproject, and then we can show the diff in env vars
more faithful?
