Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

Is it necessary to have revision or version of the parts in the Bill of Material?

If you have the ability to do an extract of the item detail for the items on the BOM, you can do an extract "snap shot" that extracts the BOM items by both PN and Rev.

Will you ever have a need to know what rev of a part was in a product you supplied to your customer long after the fact?

Can a same part number have different revision levels? If yes and the BOM is used to make sure the proper revision level for the component is identified, then, the answer for your question is yes, and the BOM should have the rev level of the part.
