Apparently not. Using your example works as expected.
RELENG_8, and RELENG_9 use short-hand;
tar -cvJ --options xz:9

Why/when the change to long-hand? Seems a shame. Now I
get to modify all my scripts, and such. :P Altho I
don't suppose it'd be a big deal to back out (revert) the
changes made to tar(1). :)

Thank you, very much, Peter. For taking the time to respond.
