Dear Thomas The reason for the asymmetry is that point coordinates are required by Unidata and COARDS conventions, whereas cell bounds were introduced by CF. Most of the new features introduced by CF are not mandatory, only recommended.
I agree that it would be helpful if we made a definite recommendation for the values of the point coordinates, for the case where the data-writer does not know what to choose. It is important that sensible coord values should be provided, since generic applications may not consult the bounds. We could put a recommendation at the end of the preamble to Sect 4. I'd say the mid-point is the obvious choice. What do you think?
