Well lets start by addressing the elephant in the room, the manufacturing module really should have been spruced up and improved, this is long overdue. A lot of customers are having to pay extra to move to 3rd party providers providing manufacturing bolt ons because just applying the odd sticking plaster on Manufacturing every so often isnt really enough. There are countless improvements that can be done, and a number of years ago it was a public secret by some product managers (who said this to numerous partners) that they were hoping that the module could be improved/rewritten. Its probably overdue and with sufficient improvement, customers could save money from having to purchase 3rd party addons.
