It is, unfortunately. I merged the tunable only a few days ago.

Glen, do you think this warrants an errata notice? I think it'd be
necessary to disable mfi(4) using something like

hints.mfi.0.disabled="1"

in order to use mrsas(4) on 9.3. That's a bit more heavy-handed than the
mrsas_enable tunable, since it prevents mfi(4) from attaching even if
mrsas(4) doesn't support the controller in question.
