    Description

      The flag PLUGIN_VAR_DEPRECATED that was implemented in MDEV-27730 works only partially. No deprecation warnings are being shown on server startup! Here is a simple test case:

      ./mtr --mysqld=--plugin-load-add=ha_example --mysqld=--example-deprecated-var=1 mtr-example.self
      		 
      grep -i deprecated var/log/mysqld.1.err

      10.3 e51a1d6fc0c105d56c6f05efb3d9fd05b7e4f22f

      		 
      $ /dev/shm/10.3/sql/mysqld --defaults-group-suffix=.1 --defaults-file=/dev/shm/10.3/mysql-test/var/my.cnf --log-output=file --plugin-load-add=ha_example --example-deprecated-var=1 --core-file --loose-debug-sync-timeout=300

      Note that there is no warning for specifying a deprecated parameter on startup. This kind of defeats the purpose of giving an early warning about parameters that are going to be removed, such as MDEV-27735 or MDEV-29983.

      Before 10.7, the flag was only used by the "example" plugin. In 10.7, it was used in the Spider storage engine, and in 10.9 for InnoDB.
