The "session_handler.write_check" service relies on the deprecated "Symfony\Component\HttpFoundation\Session\Storage\Handler\WriteCheckSessionHandler" class. It should either be deprecated or its implementation upgraded

Problem/Motivation

Core should not trigger deprecation warning during regular operation. Symfony has deprecated Symfony\Component\HttpFoundation\Session\Storage\Handler\WriteCheckSessionHandler but we are still using it.

Proposed resolution

Remaining tasks

User interface changes

None

API changes

Hopefully none.

Data model changes

None
