This would seem to be a problem for the View's Key requirements when it performs an SQL update. Is this true? Would the 'Update using' options of "SQL DELETE then INSERT" versus "SQL UPDATE" make a difference in this case?

No,
That way you just delete all records that have same values in fields and insert only one.
