It's enabled in Fedora but I've never had a huge amount of luck with
it, I would be OK with the firmware driver to disappear when ever.

From our point of view I'd sooner we can just move to the unicam in
kernel one sooner rather than later even swapping one for the other in
staging to get the libcamera one in and improve it in kernel via the
staging process, I feel that would be better use of the very few
cycles I have for RPi bits.
