This is not correct in my view. Could you explain your reasoning behind this change? I accept that we have not enforced/checked the assumption that the specified default ```coord_name``` is a standard_name (and we should add that logic), but this change will mean that if the standard_name is not specified in the cf variable but I provide a ```coord_name``` that is a standard name (e.g. longitude), it will be put in long_name, not standard_name.
