Allow changes to unsubscribed email addresses

When a contact is marked "unsubscribed", NO data fields about the contact can be updated.  This makes sense for the email address and lists they are on.  But we should be able to update other fields in the Contact record even when status is "unsubscribed".  Example 1:  Person has recently died, and someone in their family or estate handling did the unsubscribe action on most recent email.  We would like to add Tag "deceased" to the record so we know WHY they are unsubscribed.  Example 2:  Sometimes data in our customized fields is entered "not to standards".  Such as contents should be arabic numeral (like 4) but was entered as roman numeral (IV).  Or with prefix (like K4).  We would like to fix this information to fit standards to make our reports about the group easier to do.  Before massive change/update to CONTACTS functions a year or so ago, we could still make such updates to fields not related to actual sending of emails.  We would like that capability back again.
