My issue with the internal forum solution is related to your apparent position.  A particular couple find a sympathetic Priest.  Several years later the Priest is transferred, or dies, or otherwise leaves the scene and a new Priest takes up his post--the new priest is not sympathetic and causes a ruckus imposing his judgement on a beloved and loving couple.

The Internal forum solution, which comes without some sort of canonical certification, leaves the faithful at the unreliable mercy of a peripatetic clergy.
