Yes, it would if image recipe is unique, i.e. images of the same type
can be produced for different recipes.

WKS_FILES makes sense to set only if there are multiple wks files that
can be used to produce an image. The most obvious use case is using
multiple layers with different wks files in each and specifying all of
them in WKS_FILES.

If this is not the case then setting WKS_FILE is enough.
