Is the intent that successive versions of the tzfile format will be compatible with older implementations of localtime.c, date.c, etc.? Obviously they wouldn’t be able to take advantage of any new information, but is the idea they’ll still be able to read it?

I wasn’t able to find anything in the man pages about this.
