The real issue here is the disparity between a crafted piece and the prototypes. Granted the BAW 7 Armor mod takes 1x mk2 fabritech datapad, and 2x mk1 stun cuffs in addition to the 5 prototypes, so it should be worth a little more than 5 prototypes on their own, but doubling the value is what creates these stupid hoops to jump through. If 5 prototypes was worth ~290 scrap (or the fully crafted was worth ~160 scrap) then no one would care or bother.
But the ability to craft in gear in the salvage shop is the work around if they don't want to standardize the values.
