We cannot remove the /sys/class/firmware usermode helper, it however should be compartamentalized to only a few device drivers that we *know* definitely need it. So far there are only 2 device drivers that we've identified as needing it and as such only those drivers should implicate use of it. In the future, should the sysdata API get merged, the implications are that the further features of the firmware API will be added for sysdata users, but perhaps not for the old API as that entails silly collateral evolutions to the API or new exported symbols. I highly encourage use of the usermode helper to be reconsidered and simply abandoned. There are many reasons why it was a bad idea, for details refer to the thread [0].
