   > I noticed there is a behavior change that might impact users' applications 
if the schema auto uploading is disabled.
   > 
   > Before this change, users can delete the topic without deleting schema, so 
that the application can connect to the newly created topic with the same topic 
name and existing schema, but after this change, not able to connect to the 
topic again.
   > 
   > Hmmm, before, users usually use the delete topic to truncate data of the 
topic. After #10326 introduced truncate topic, I think for now users should to 
use the truncate method to cleanup data of the topic. So there is no reason why 
the user still wants to use this topic, but also delete it.

   I have added explanation in the CLI / API doc.
