Removing that and keeping the dkim signature intact is a good thing. The goal should be that we can reject any dkim failing messages and the only thing that stands in the way there are maling lists which are still misconfigured. > Some mailing lists don't use such an identifier in the subject, but a > lot of mailing lists for good reasons do.

Assuming the dkim signature covers the subject, which is always the case for any reasonable setup, it being a somewhat sensitive header. > For example, if you have got a virtual search folder with a filter, that > searches the email bodies for "x11" in folders for different mailing > lists, it can be very helpful, if the subject lines mention "[arch- > general] ", "[Alsa-user] ", "[Evolution] ", "[lubuntu-users] " etc. to > get a first overview. Filter on the List-Id: header, that's what it is meant for. Any email that arrives in your inbox from the list, also has the list address on its recipient list, so it's easy enough to filter based on that as well if you don't have a MUA that can read headers.
