dynamically enable/disable binlog

This task would be to re enabling dynamic global binlog setting in MariaDB ?

set global log_bin=OFF;
Variable 'log_bin' is a read only variable;

Most common scenario are

• production server that simply can't be restarted and need to become master
• Spider, Galera can control binlog to resync node (removing gcache)
• Dynamic auto configuration scripts
• Fail over scripts can promote a slave that as no binlog

SQL_LOG_BIN can be use for SESSIONS and LOG_BIN=0N for GLOBAL
We get the best of all world and no risk of confusion.

Other solution would be to introduce new GRANTS
GLOBAL BINARY LOG

Thanks
