This isn't so much as bug/issue as it is a discussion...

I'm trying to figure out why this project is using a wrapped Doctrine connection

instead of allowing the PdoSessionHandler to create its own connection as suggested by the symfony docs
https://symfony.com/doc/4.4/session/database.html#store-sessions-in-a-relational-database-mariadb-mysql-postgresql

Can anyone shed light on this?
