When Baseball Prospectus was first getting started more than a decade ago, we created a statistic, pitcher abuse points, in an effort to learn what sort of workloads starting pitchers could handle. Controversial at the time because of the inference that it was a predictive tool, PAP was in fact a counting stat, sort of like a warning light on the dashboard of your car -- it gave you cause for concern but didn't tell you a complete breakdown was incipient. However, when PAP was first published, the baseball industry was relatively indifferent on the subject because pitcher workloads weren't as carefully monitored as they are now.
