Comment (by Dave.Allured):

 Replying to [comment:5 jonathan]:

 Yes, this is technically a proposal for a "new calendar".  I should have
 said this more clearly in the introduction, sorry.

 My general rationale for the new calendar name is two-fold.   The first
 purpose is simply to improve the quality of self-documentation of data
 sets.  CF should have a simple way to declare explicitly and deliberately
 that the mixed Julian/Gregorian calendar is being used.  Currently there
 is no standardized way to do this.

 The second purpose is to provide a transitional alternative, a mechanism
 to make it easier to deprecate previous calendar names and usage, where
 there can be a consensus that previous usage is bad practice or bad
 design.  This new calendar name could be easily substituted for previous
 "inadequate" calendar names in many existing data sets, as needed, with no
 recomputation of time coordinates or other adjustments.  With a reasonable
 alternative and the ability to retrofit existing data sets, some people
 may be able to accept more significant changes, such as removing the
 default calendar.

 I tried to explain this rationale in other words above, under
 "Requirement" and "Benefits".
