FWIW, I'm preparing a few small tweaks for
Documentation/process/stable-kernel-rules.rst (to be submitted after the
merge window). I among others consider adding something like this that
might help avoiding this situation:

```
To delay pick up of patches submitted via :ref:`option_1`, use the
following format:

.. code-block:: none

     Cc: <stable@...r.kernel.org> # after 4 weeks in mainline

For any other requests related to patches submitted via :ref:`option_1`,
just add a note to the stable tag. This for example can be used to point
out known problems:

.. code-block:: none

     Cc: <stable@...r.kernel.org> # see patch description, needs
adjustments for 6.3 and earlier

```

Greg, if this is stupid or in case you want it to say something else,
just say so.

Ciao, Thorsten
