1. Remove modification of the emails on the lists server so that DKIM

Yes, please, but for different reasons:

Filtering is much more reliably performed using the 'list-id' header compared to a Subject prefix and not having the prefix in the Subject makes the INBOX more tidy when also having the [RFC] or [VOTE] prefixes. Also clients apparently can't decide whether to put the 'Re' before or after the prefix. DMARC is less of a concern, because the list apparently already performs DMARC mangling for a policy that is not 'none'

Apart from (possibly) modifying the body and the subject line which then breaks the DKIM signature which then breaks DMARC ;-)
