Yes, creation of a MARC record does not mean data has been entered
into it (assigned), nor that it has been applied by an ILS (utilized).

The word "used" is ambiguous; it can imply either applied or utilized.

It seems to me ILS utilization is far more relevant to Bibframe design
and crosswalk from MARC, than assignment.  What's the point of
transferring an element from MARC to Bibframe (no matter how
prelevant) if not utiliZed in ILSs?  Why consdider dropping an element
(regardles of how rare) which is always utilized if present?
