I believe one powerful motivation for the outboard supply approach is that it exempts the manufacturer from having to put the entire assembly through the various safety and regulatory processes (UL, CSA, CE, etc.). He can instead put the regulatory burden on the subcontractor who furnishes the supply. This can save LOTS of money when bringing a new electronic product to market.
