Not too likely given that the need for one-off resources for a specific
driver seems to indicate lack of proper abstraction and control mechanism
more than anything else. Even for cases where there are genuine needs for
per-hardware knobs, I think it's prudent to enforce a review cycle which
involves people who aren't directly working on the specific driver.
