Jeff,
That is a business decision. It may be that your proposal could result in a BOM maintenance strategy that makes it a bit simpler for the master data people, but I don't know enough about your company, and your other products, to speak competently in this area.
Functionally, though, the most important thing about BOMs is the ratio between the base quantity of the parent material and the bom quantity of the components. There are many ways to set up your BOM that will ultimately explode in exactly the same way when MRP runs. Any BOM maintenance strategy that you create that complies with the ratio is OK by me.
