It means that you can add headers, but should avoid changing headers that
are already present. DKIM signatures generally cover those headers that
already present in a message, and leave room for additional headers.

The addition of "List-" headers does not break DKIM signatures, as origin
DKIM signatures do not cover these (absent at the origin) headers. (I'm
over simplifying, but the fine points are not important here).

Some people really want subject tags. If they can do without, it is
easier to avoid DMARC trouble, provided they can also do without footers.

Both the footer and subject tags would need to go. There's no point in
changing just one of the settings. The DKIM signature covers both the
message headers (as present at the origin) and the body content.
