In the existing code - no.
But I would appreciate if e.g. sysctl -d could report that a sysctl also has a
twin tunable.  I can imagine that there could be things which are better be set
to a certain value from the very start (via a tunable) rather than switched to
that value later in a boot process (via sysctl).
Extra user-friendly information doesn't hurt, IMO.
