That was my intention as I wrote the bug report. To be able to use 
mysql_upgrade with the MySQL database that is maintained through the mysqld 
process Akonadi starts and stops by itself for each user session.

I am not sure which other use cases exists tough for skipping the use of the 
maintainer scripts. One case is when you want to have mysqld be running as 
ordinary user instead of as root, storing the data within the user home 
directory or elsewhise and being able to backup and restore the database with 
ordinary user rights this way. Whether someone else does this I don´t know.

Thanks,
