Agreed.  There have been no changes since we discussed this.

The best proposal was to renumber the newly-found items to the end of
the numeric range for the pre-July 2006 archives, and to properly number
July 2006 and later archives.  And this date range has to be enbedded in
the archive script so if it is ever run again, this behavior continues
to happen.

The longer we take to fix this, the more likely that people are creating
URL's that refer to the existing pre-July 2006 numbering which should
change.  It needs to be fixed quickly.

And we can't just leave it alone because old archive emails have URLs
that point to now-incorrect numbers, and there is no good way to fix
that everywhere are emails are archived.
