Description
Over the time and different versions, some structures in mysql schema get changed, but not all the changes make it to the scripts executed by mysql_upgrade. It means that a schema freshly created by mysql_install_db on a version 10.x.y differs from a schema created on an earlier version and upgraded to 10.x.y by mysql_upgrade.
All diffs below are from diff -u <upgraded schema> <newly created schema>.

This is not a miss, but a difference worth mentioning. With the same 10.4 build in the same environment, on a newly created schema I get mysql.user with charset latin1, while upon upgrade from 10.3 – with utf8.
