The spec is intended to address bibliographic data, but it isn't limited to bibliographic data, and there are several other disciplines represented.  For example, astronomers may want to discuss the pending collision of the Andromeda and Milky Way galaxies, to occur in the year three billion.....

... which of course wouldn't be supported by 6-digits, and the fact is, 6-digits was chosen arbitrarily and as a placeholder, as there has been no discussion of the matter, yet. 

There may be no requirement beyond 4-digits, and if we can ascertain that that is so, it would make matters much simpler and I would be glad to see expanded years profiled out.

So I welcome discussion of this.
