Yes, that's the only use for CTLFLAG_TUN _now_.
Perhaps in the future there could be other uses, such as a flag to sysctl to list
names which are also tunables. Or some other creative use.
CTLFLAG_TUN Also declare a system tunable with the same name to ini‐
tialize this variable.
While the above is not true or very ambiguous at the very least, I still don't see
any reason not to use the flag in this case.
