Cannot disable CI Session handling in v4.5.1

Flash messages, the built-in Referer, temporary _POST data, and validation errors during redirects will stop working...
You can try to change the CI4 class and divide the sessions by names in some way. For example, $_SESSION['old']['key'] and $_SESSION['ci']['key']

It all looks stupid. You can't time out the old code, but you have time to invent a crutch.
