Have you read it?

GP1: "Describe all the radio frequency parameters that are modified by any software/firmware without any hardware changes. Are these parameters in some way limited, such that, it will not exceed the authorized parameters?"

3dP1: "Explain if any third parties have the capability to operate a US sold device on any other regulatory domain, frequencies, or in any manner that is in violation of the certification"

3dP2: "What prevents third parties from loading non-US versions of the software/firmware on the device? Describe in detail how the device is protected from “flashing” and the installation of third-party firmware such as DD-WRT."

They don't care that people can install DD-WRT because of DD-WRT they care about it because it bypasses vendor restrictions if DD-WRT comes up with a way to comply with the regulatory domain, or if the vendor explains that DD-WRT will not be able to modify the Wireless Parameters out of the spec of the US regulatory domain due to limitations on the radio SOC it self they won't care if you can install DD-WRT.

Yes, I appreciate that the FCC's proposal imposes the fewest possible restrictions, but you'd be crazy to think that it will work this way in practice. It's far easier to comply with FCC regulations by preventing any modifications whatsoever than to lock down the specific modules.

Really depends on how the open firmware community decides to handle this, if they'll put their heads in the sand and say well FCC are bad and write to your representatives nothing will come out of it. If they work out a framework to prevent misuse of regulated equipment there's a good chance that thats what we'll see implemented.

And locking out the firmware might not be the easiest way to handle this if you are a manufacturer since you'll still need to provide updates and multiple software versions (even basic things like ISP branding), so you'll have to resort to using cryptography building in a secure boot/secure flash mechanism and such and such which isn't cheap to maintain, for you telling broadcom to just disable Channel X Y and Z in their radio might be a cheaper and easier option.
