Is Zerodha shutting down MIS & CO product from August 2021 for F&O segment?

Is Zerodha closing all MIS/CO products from August 2021 in F&O segment?

There will be no changes in Order types offered. You will be able to use MIS, CO as you currently are using.

If margin requirements will be the same in Normal order & MIS order, then is there any benefit with using MIS product? If no, then why would Zerodha continue with MIS?
