> Can someone remind me why any of the above is better than using ECPointFormat to specify the point format?

Because ECPoinrtFormat requires X and Y cords and Curve25519 has no Y.

There is discussion about having a "defined by the curve" ECPointFormat; how to move such a proposal forward is being discussed by the Security Area Directors, who owe as a response "soon" (see http://www.ietf.org/mail-archive/web/tls/current/msg11139.html )
