Seems a bit suspect, but as your script doesn’t mention tar the option
itself is apparently ignored, I guess silently.  Assuming this isn’t an
actual regression in behavior in a patch-released older version I don’t see
us adding an error message at this point.

Support wasn’t removed.  Re-read the email and check the version/times
being mentioned again.
