fun story: security-bundle@6.0 requires security-core ^5.4 | ^6.0 ; tests were perfectly fine when I added the User provider, even with lowest deps.
But it should not have been this way: the interface for the UserProvider was different in security-core 5.4 (loadByUsername became loadByIdentifier in 6.0). Tests were green even with security-core 5.4 ; but not anymore. So we lock the core at 6.0 minimum to avoid that.
