When is `ROT_FOUR` used as of today?

I read the old issue from 2004:
https://bugs.python.org/issue929502, which says:

that the ROT_FOUR opcode is only used in one incredibly obscure situation…
augmented slice assignment (and then only when the slice has exactly 2 arguments). In case it’s not obvious what augmented slice assignment IS, here’s an
example:

>>> x = range(6)
>>> x[2:4] += 'abc'
>>> x
[0, 1, 2, 3, 'a', 'b', 'c', 4, 5]

So I tried it in Python 3.8, and didn’t see ROT_FOUR

>>> dis("x = range(6); x[2:4] += 'abc'")
  1           0 LOAD_NAME                0 (range)
              2 LOAD_CONST               0 (6)
              4 CALL_FUNCTION            1
              6 STORE_NAME               1 (x)
              8 LOAD_NAME                1 (x)
             10 LOAD_CONST               1 (2)
             12 LOAD_CONST               2 (4)
             14 BUILD_SLICE              2
             16 DUP_TOP_TWO
             18 BINARY_SUBSCR
             20 LOAD_CONST               3 ('abc')
             22 INPLACE_ADD
             24 ROT_THREE
             26 STORE_SUBSCR
             28 LOAD_CONST               4 (None)
             30 RETURN_VALUE

Can someone give a case where it is used ?

Seems it was added back by https://bugs.python.org/issue17611.

Still, hoping to see a real example.
