I don't necessarily disagree with this assertion, but what this could
lead to is a proliferation of a bunch of very similar images.  Templatizing
some of the attributes (e.g., this package is enabled, that one isn't)
can reduce the potential explosion of images stored in glance.  If that's
a concern, then it needs to be addressed.  Note that this is true whether
tuskar does/helps with the image building or not.
