    Description

      plugin variables (MYSQL_SYSVAR and MYSQL_THDVAR) can provide a validation callback, it's invoked on SET checking whether a value is valid and can be assigned.

      But for SET var=DEFAULT it's not invoked, and while normally a default value can be expected to be valid, it doesn't necessarily mean that it can be assigned at any arbitrary point in time, for example, a variable might be read-only inside a transaction.

      validation callback must be invoked for =DEFAULT assignments too.
