How can I permanently delete customer tags?

Hey Shopify team - I’m another customer in need of this. Can you please provide an update on when this will be possible?

We use Mailchimp for emails, and they have a 5,000 tag sync limit in their system. In the past thousands of tags were generated that are no longer needed, so we deleted the tags, but they still show up. It’s preventing us from continued email marketing campaigns for new customers.
