So this allows you to include 'a directory' as source of a partition
to be created, right?

If my understand is right, I like the feature. My only concern is
people overusing it and adding contents which are not 'tracked' in the
build system in a product release which seems attractive when we first
think about it but cause some management, tracking and authenticity
check problems in long term.

I don't know how to better address this from wic perspective. Usually
we end doing multiple images as part of the build process for those
special cases and I don't know how wic could be 'told' about those
secondary rootfs existence.
