Hell No! You can fork firmwared or use whatever the hell bin-foo you want.
Even if its proprietary and glued with evil rainbow unicorns on it.  The dual
mode, best-effort mode and final-mode devices it implemented are key to what
you want to mimic as an example to achieve the goal in question.

Please give that thought / architecture solution a spin and let me know if
it suffices for your needs.
