"enabling manufacturers to lock you out of the devices you bought...."
When a device presents physical threats to others, it may be the right thing to do. Because people messing up with devices may make them even less secure and more dangerous than the OEM - and would they adhere to standards? Who would inspect and approve user-modified devices?
Just like governments, anarchists and tinfoil hat wearers are not good at writing regulations.
