Oh, cool!

I expected 6.0.9 to contain the fix though:

Yeah right, even if it is fixed earlier, it's at least 6 months.

Right, the help text needs to be changed. There are distros like Red Hat
which don't support !DEPRECATED at all today, so we should probably just
remove the date and add that to the help text.

On the other hand, we are currently considering making the DEPRECATED
behavior a boot-time option, so it can be changed on the kernel command
line instead of a compile option. There would only be a compile-time
default to set.
We will get to that after the current kobject work (~100 patches) in
Greg's tree is finished.

Thanks for your help and patience,
Kay
