Why is there a modify order endpoint for Coin-M Futures but not USD-M Futures?

Modify order endpoint is quite elementary, and most exchanges implement it but I don’t understand why Binance doesn’t for USD-M Futures. The alternatives of cancelling and sending in a new order creates race-conditions where the order gets filled before the cancellation request reaches the server.

It seems that Coin-M Futures have this feature but USD-M Futures doesn’t. Why is this?

It is in the plan, but no ETA.
