I would guess the problem with business as usual is that the cost magnitude of doing this means that only companies throwing off serious cash are doing this. Which has the side effect of their solutions being bespoke, because acceptable cost looks like "Tell me when I need to stop adding zeros to make this happen." To go another way you either (1) need to be Amazon-scale already (i.e. "there aren't enough zeros to make inefficiency worth our time") or (2) be willing to say no to huge profits out of ideological purity. The well-funded client / custom trap is real.
