We're experiencing some troubles finding out how we can limit on a per API basis, a message size limit.

We ran a few tests and you'll find below results.

Is this what is expected and above all is this behavior likely to change in a future version ?

We are implementing security policies for each project to use as per policy header, somewhat a mandatory policy, that will indeed include message size limitation based on project's inputs.
