Symfony 5.1 introduced an [updated security system](https://symfony.com/blog/new-in-symfony-5-1-updated-security-system). Re-scheduled this ticket for 4.0.

Closing as won't fix. Let's just share stuff on demand.

Closing as migrations can/will be used per bundle as part of replacing the old extension installer interfaces.

For some potential causes of errors see #3750

The menu module should provide means for displaying/handling multi-level menus. See https://github.com/zikula-modules/Content/issues/296#issuecomment-422672003 for examples.

Not needed anymore as dynamic menus are gone.

This does **not** work. See #4354 for how it works.
