If userspace can somehow obtain a persistent address, it can kick
udev too.
I really don't see any real value provided by letting userspace mess
with this. Because the permanence communicated in this value is from
the perspective of the kernel driver, it's really therefore about the
thing that's in ->perm_addr[] not what happens to be in ->addr[] right
now.
