It's better this way because the RandR case has to be supported by the tools
anyway. Because there are drivers for which there is no kernel backlight
driver. One example is intel legacy - it's still exposed by the intel xorg
driver.

You remember there *were* standardization processes running to get audio over X
working. They were all broken by design, though, as far as I remember, but many
people would still love to see this happen. Unlikely any time soon (or later),
though.
