No, this is incorrect. Body should be either read or discarded
before response could be returned (else communication with clients
which write body and only then read response will just deadlock).
And it's up to code returning response to decide whether it needs
body or not, post_action has nothing to do with it. (I personally
consider post_action to be a dirty hack which should be removed
entirely, and it's not officially documented on purpose, but
that's another story.)

In you particular case I would recommend actually using module to
read body and return 202 response instead of using "return 202".
