Exclude user modifications from replication

I am running a MySQL database that is replicated to multiple instances for various purposes.

I want to distinguish database users between Master and Slaves. Users that have access to the Master should not automatically have access to all replication Slaves. On some slaves I would like to configure users that do not have access to the Master.

To achieve this I have excluded database "mysql" from the replica. However, I noticed that user modification queries (CREATE USER, ALTER USER, DROP USER) are still replicated to the slave. If I create a user on the Master it will also be created on the Slave. And, more importantly, if I drop specific users from the Slave and not from the Master, and then modify the users on the Master, this will lead to a replication error. Also, creating a user on the Master that already exists on the Slave will lead to errors.

Is there a way to exclude all user modification queries from the replication?

Is it a good idea to exclude the entire MySql database from replication?
