Why after customer deletion, mailchimp disconnect/connect need to perform?

[NiteshKuyate]

We had installed Mailchimp 1.0.26 to Magento 2.1.5

After deleting a customer in Magento admin, revenue statistics in mailchimp doesn't show anything after the date of customer deletion, then getting

Resource Not Found : The requested resource could not be found.

After that we update Mailchimp extension to 1.0.27 then above issue resolved.
But after deletion of customer again that issue appear.

We are wondering if in the future we need to delete a customer would deleting the customer first in MailChimp and then Magento admin prevent this same 'extension updation' from happening again?
