When the in cases where the productivity measurement scheme is this straightforward, you'll find a lot of positions offer bonuses or incentives for hitting metrics. Or maybe just quotas that serve to inform the worker that any addition work is unnecessary. After all, you pointed out all the obvious reasons that this makes sense.
The reason the vast majority of jobs don't work this way is because productivity is rarely: A) so easily measured B) so easily mapped to revenue. A 0.1x person whose maintenance work generates real revenue contributes more to the bottom line than a 100x worker in the same position whose project is scrapped for whatever reason.
