What

The set of reasons a session-to-session message can be refused no longer includes a feature-flag one, and the check that tested for it is gone. Refusals now come only from deployment, policy and authentication rules.

Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
