[xoa]

I too would definitely be interested if there's any sort of milestone planned for X25519. There are a couple of open enhancement requests on it in both openbsd and portable [1,2] dating to before ratification of RFC 7748 (or Chrome 50), but no assignees yet. I also don't see any discussion on the libressl public mailing list archives at marc.info, though I'm not sure if that's complete. It seems like it may become an ever bigger breaking issue for a lot of folks as support becomes more widespread following standardization, inclusion in OpenSSL 1.1.0, and increasing major browser/OS support.
