(1) BidManipulation is only used in some testing/market simulation environment.
(2) only used in cases where some pricing bug/weird legal issue happened that needs some tweaking to be corrected.
(3) only used in some weird markets where it is legal.
(4) implement many weird obscure features for "next generation ad experience marketplace stuff" and push them to production leaving it to higher ups to configure which combination of them are being used at which market.
(5) empower engineers to come up with additional "whacky ideas" and keep a culture where it is assumed that almost all of them are not passing legal review but they could be enabled at any time.
Not a recommendation.
