Yes, both of these are real fears for those of us heavily involved in a lean transformation.

When we hit the wall one of two things happens.  Sometimes the lean program gets a back seat and dies a slow death and in other cases the CEO wants lean spread fast with direct accounting for bottom-line results.  Then we get cookie-cutter lean (e.g., spread the kanban, standardized work sheets everywhere, etc.) and managers who are accountable for results or else.  Often that means lean audits of various kinds.
