This patch will export the supported commands by the devices

I think this is not the reason why this was implemented. You check here
cfg802154_ops which ends in mac802154 (SoftMAC) OR _possible_ HardMAC drivers.
If you want to make sure that a driver implement it _and_ really sure
you need to check on ieee802154_ops.
I suppose the real reason why wireless has this implementation, is
because to check if HardMAC drivers can support a specific command.
This is because every HardMAC driver should implement then the full
cfg802154_ops callback structure. It's simple wrong here to say "to
check if the driver support the functionalities".
I found this thread for the reason used in wireless for implementation.

You skip the mac802154 layer here, these calls are direct driver-layer
calls in case of HardMAC driver only.
Currently that's why I think such feature has _at_ _the_ _moment_ no
really big use case, because we don't have any HardMAC driver currently.
Anyway this prepares to handle HardMAC drivers. After fixing the commit
message you can add a:
