Might a governmental committee mandate that law departments provide benchmark data?

An article about the costs of e-discovery raises an idea regarding mandatory collection of data from law departments and what they spend for litigation and on e-discovery. “It would do the [Federal Rules Advisory Committee] good to collect data on that subject and corporations should be willing to provide it.”

Government collected metrics on legal department spending! An exciting thought from Met. Corp. Counsel, April 2010 at 9. Whether it will come about I have no way of knowing, but I am not holding my breath.
