Slight clarification 9.0 doesn't - current versions of 9.0_STABLE do,
and 9.1 will.

The test treats 9.0_STABLE the same as 9.0. That could be adjusted at
the expense of triggering nasty crashes for 9.0 and older 9.0_STABLE
users, but will not help anyone on 8.x (I'm running a build with the
test modified now on up to date 9.0_STABLE to see if it does change
the behaviour)
