1) Russ and I made a new version of this background document: http://www.unidata.ucar.edu/software/netcdf/papers/nc4_conventions.html
2) I posted an issue, you should have gotten a notification if you are signed in and "watching". Go to: https://github.com/cf-convention/CF-2 and look for the "eyeball" icon (upper right) and see if you are watching or not.
