This is meant to encapsulate the tweaks we do to the OS tree orthogonally to anything else. For now it still contains some configuration that only sometimes applies, but this should continue being reworked until all the fields in this struct always apply to any artefact that is using it. At the same time, stop instantiating with default values, as the empty values should work. This is not a functional change as the caller always sets these now.
