Yes, any recipient who is using DKIM would probably find the header clean-up unattractive, since it would cause DKIM to barf on any signed messages on which the list server didn't cause trouble.

The list server needs to be configured not to modify any headers signed by DKIM. This includes not changing the Subject header. In my configuration, and this is probably typical, DKIM verification is done during the SMTP transaction, before the message is delivered to Procmail. Messages which fail the check are bounced at that point.
