Not Using Admin Default Footer – Any Negative Side Effects?

Hello,

We are creating new email templates and wondering if there is any reason we should use the Admin default footer area. We are considering making custom footers per email, and we want to make sure there won't be any deliverability or technical issues, if we bypass the Admin default footer feature. Our current templates use the Admin default footer, but our emails are becoming more complex, and we need more than one footer for non-operational emails. Thank you for any insight!
