XCU, stty, CHANGE HISTORY, Issue 6, para. 1 implies -xcase is still available

Hi!

Quoth Issue 8 Draft 2.1, XCU, stty, CHANGE HISTORY, Issue 6:
  108300        The LEGACY items iuclc(−iuclc), xcase, olcuc(−olcuc),
            lcase(−lcase), and LCASE(−LCASE) are
  108300        removed.

Compare SUSv2, Commands and Utilities, stty, OPERANDS, Local Modes:
  xcase (−xcase)
    Set canonical (unprocessed) upper- or lower-case presentation. This
    has the effect of setting (not setting) XCASE in the termios c_lflag
    field, as defined in the XBD specification, Chapter 9, General
    Terminal Interface. (LEGACY)
(whole paragraph shaded EX).

XCASE was removed in Issue 6 as well, so, naturally, -xcase makes no
sense, and, indeed, there's no mention of it.

However, the CHANGE HISTORY would imply that,
if you read it retrochronologically, -xcase never existed, or,
if you read it prochronologically, -xcase was removed in error.

Best,
