In general, you don't want to do this since SPF/DKIM/DMARC will break if you do, which leads to the issue of mail being sent to the list, being modified by the list, being sent to subscribers, being evaluated as spam for failing SPF/DKIM/DMARC. There's a few lists that still do modify the subject and/or body of the message to add list information, and I personally cannot send to them because of this. E-mail literacy is just something that ought to be taught because clearly people don't know how to read the (additional List) headers, which includes a List-Unsubscribe header indicating where to send leave requests. Kusoneko.
