No, right now, the parser is not used anywhere in the openser code.

The entire parsing is done just like for the other SIP headers, inside
the PKG_MEM.
The cloning functions are provided for modules that will want to keep
a copy of the parsed SDP in SHM_MEM.
The purpose of this cloning methods is to provide the ability to match
the SDP offer with an SDP answer inside the same transaction or
dialog.

You are correct, there is no stateful support right now.  It will be
the job of a module to provide stateful support by using the cloning
functions.
