I could not find a way to set a value of this preference. Is it used available anywhere?

It's an advanced preference in the "Compose" preference group.

Do you have a deprecation policy, when this property can be removed?

It is already removed, as a settable preference. We don't remove migrations though.

The allowed_classes option is added with PHP 7.0, so we can only use this in IMP 7. For IMP 6, we need to find a different solution. Or at least do a version check. |

This patch appears to be broken as-is. See tribut@2e27df5, tribut@8a81c3b and tribut@2a9f221, maybe more additions are needed.

This needs to include 'IMP_Flag_User' as well as the 'IMP_Flag_System_' classes (not sure about all of them, we've seen errors without IMP_Flag_System_Unseen at least).

I want to resolve ZDI-20-1051 vulnerability (additional details) using json serialization when possible and the list of allowed classes in other cases.
