Schema Registry force delete and recreation updates the version

Hi, Looking at the confluent docs Schema Deletion Guidelines | Confluent Documentation
I have tried hard/force deleting schema registry using API with appending
“?permanent=true” but on recreation of the topic, I see the version gets updates from version 1 to 2!
I expect it to be version 1.
Please let me know why this could be the case? Also, suggest how to get back the topic with version 1 in schema registry!

Eg- Using DELETE on https://[schema-registry-url]/subjects/versions/6/[my-existing-subject]?permanent=true

@rmoff, Any updates on api for hard deleting schema versions?
